Use Mnemonics in Studying


Mnemonics are memory aids that can help you remember and recall information more effectively. They are especially useful in studying when you need to memorize facts, formulas, dates, lists, or any other information that might be challenging to remember. Here's how you can use mnemonics in studying:

  1. Acronyms: Create acronyms by taking the initial letters of a list of items you want to remember and forming a word or a phrase. For example, to remember the Great Lakes in North America (Huron, Ontario, Michigan, Erie, and Superior), you can use the acronym "HOMES."

  2. Acrostics: Similar to acronyms, acrostics use the first letters of a list of items to create a memorable sentence or phrase. Each word in the sentence represents the first letter of the items you want to remember. For example, to remember the order of operations in mathematics (Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction), you can use the acrostic "Please Excuse My Dear Aunt Sally."

  3. Visualization: Create vivid mental images related to the information you want to remember. The more absurd or humorous the image, the easier it will be to recall. For instance, to remember the steps of the scientific method (Observation, Hypothesis, Experiment, Analysis, Conclusion), you can visualize a scientist observing a flying hippopotamus, then forming a hypothesis about its flight, conducting an experiment, analyzing the results, and finally, drawing a conclusion.

  4. Chunking: Break large chunks of information into smaller, manageable groups. For instance, if you need to memorize a long series of numbers, divide them into groups of three or four digits. It's easier to remember smaller groups than trying to memorize a long sequence at once.

  5. Rhymes and Jingles: Create rhymes, songs, or jingles that incorporate the information you want to remember. The rhythm and melody can make the information more memorable. For example, to remember the number of days in each month, you can use the classic rhyme: "Thirty days hath September, April, June, and November..."

  6. Storytelling: Construct a story that includes the information you need to remember. Make it engaging and memorable, so the information becomes woven into the narrative. Our brains are wired to remember stories better than isolated facts.

  7. Memory Palace (Method of Loci): This technique involves mentally placing the information you want to remember in specific locations within a familiar place, such as your house. As you mentally walk through these locations, you can recall the information associated with each place.

  8. Flashcards: Create flashcards with a cue on one side (e.g., a question, keyword, or term) and the answer on the other side. Review the flashcards regularly, focusing on the ones you find more challenging.

Remember to use mnemonics in combination with other study techniques, such as active learning, regular practice, and repetition. Different mnemonic strategies work better for different people, so experiment and find what works best for you. Mnemonics can significantly enhance your ability to remember and retain information, ultimately improving your performance in exams and academic pursuits.

How to Use the Simple Interest Formula


Glow Images, Inc. / Getty Images

Using the simple interest formula is straightforward and can be applied to various financial scenarios. The formula for simple interest is:

Simple Interest (SI) = Principal (P) × Rate (R) × Time (T)


  • Principal (P) is the initial amount of money invested or borrowed.
  • Rate (R) is the interest rate per period. Make sure to use the rate as a decimal (e.g., 5% should be written as 0.05).
  • Time (T) is the number of periods the money is invested or borrowed for.

Follow these steps to use the simple interest formula:

Step 1: Gather the information Collect the necessary data for the calculation:

  • The principal amount (P).
  • The interest rate per period (R) as a decimal.
  • The time period (T) for which the money is invested or borrowed.

Step 2: Plug the values into the formula Insert the values into the simple interest formula:

Simple Interest (SI) = P × R × T

Step 3: Calculate the simple interest Multiply the principal (P) by the rate (R) and the time (T) to find the simple interest.

Step 4: Find the total amount To calculate the total amount (A) after the specified time, add the simple interest to the principal:

Total Amount (A) = P + SI

Example: Let's say you borrow $1,000 from a friend for 3 years at an annual interest rate of 4%. Calculate the simple interest.

Step 1: Gather the information

  • Principal (P) = $1,000
  • Rate (R) = 0.04 (4% expressed as a decimal)
  • Time (T) = 3 years

Step 2: Plug the values into the formula Simple Interest (SI) = $1,000 × 0.04 × 3

Step 3: Calculate the simple interest SI = $120

Step 4: Find the total amount Total Amount (A) = $1,000 + $120 Total Amount (A) = $1,120

In this example, after 3 years, you will have to pay a total of $1,120 to your friend, which includes the borrowed principal and the simple interest accumulated over the period.

Example 2: Find 30% of 180 Break down 30% into 10% + 10% + 10%. Then, find 10% of 180 and multiply by 3: 10% of 180 = 0.10 * 180 = 18 30% of 180 = 18 * 3 = 54

Example 3: Find 15% of 360 Use the multiplication shortcut for 10% (0.10) and adjust accordingly: 10% of 360 = 0.10 * 360 = 36 5% of 360 = 0.05 * 360 = 18 15% of 360 = 36 + 18 = 54

Example 4: Find 75% of 80 Since 75% is three-quarters (3/4) of the number, you can find 75% by multiplying by 0.75: 75% of 80 = 0.75 * 80 = 60

Example 5: Find 5% of 400 Use the multiplication shortcut for 5% (0.05): 5% of 400 = 0.05 * 400 = 20

Example 6: Find 35% of 120 Break down 35% into 30% + 5%. Then, find the individual percentages and add them up: 30% of 120 = 0.30 * 120 = 36 5% of 120 = 0.05 * 120 = 6 35% of 120 = 36 + 6 = 42

Example 7: Find a 20% increase of 150 To find a 20% increase, add 20% of 150 to the original number: 20% of 150 = 0.20 * 150 = 30 20% increase of 150 = 150 + 30 = 180

Example 8: Find a 15% decrease of 200 To find a 15% decrease, subtract 15% of 200 from the original number: 15% of 200 = 0.15 * 200 = 30 15% decrease of 200 = 200 - 30 = 170

By practicing these mental math techniques, you can quickly find percentages of numbers without relying on a calculator. With time and familiarity, you'll become even faster and more accurate in your calculations.
