## Maths Shortcut Tricks

**1. Multiplying by 11:** To multiply a two-digit number by 11, add the two digits together and place the result in the middle. For example, 11 x 13 = 143.

**2. Squaring Numbers Ending in 5:** To square a number ending in 5, take the number before 5, multiply it by the next consecutive number, and append 25 to the result. For example, 35^2 = (3 * 4) + 25 = 1225.

**3. Percentage Calculations:** To find 10% of a number, move the decimal point one place to the left. To find 1% of a number, move the decimal point two places to the left. For example, 10% of 250 = 25, and 1% of 250 = 2.5.

**4. Finding Fractions of Numbers:** To find a fraction of a number, multiply the number by the numerator and then divide by the denominator. For example, 3/4 of 80 = (3 * 80) / 4 = 60.

**5. Divisibility Rules:** Learn divisibility rules for numbers like 2, 3, 4, 5, 6, 9, and 10. These rules can help you quickly determine if a number is divisible by another.

**6. Multiplying by 9:** To multiply a number by 9, multiply it by 10 and then subtract the original number. For example, 9 x 7 = (10 x 7) – 7 = 63.

**7. Finding the Square of Any Number:** To square any number, use the formula (a + b)^2 = a^2 + 2ab + b^2, where a is the tens digit and b is the units digit. For example, to square 47, use (40 + 7)^2 = 1600 + 560 + 49 = 2209.

**8. Cross-Multiplication for Proportions:** When solving proportions, you can use cross-multiplication to find the missing value. For example, if a/b = c/d, then ad = bc.

**9. Finding Percent Increase or Decrease:** To find the percentage increase or decrease between two numbers, use the formula ((New Value – Old Value) / Old Value) * 100%.

**10. Prime Factorization:** Break down numbers into their prime factors to simplify calculations involving factors and multiples.
