1.

the sum in the middle. For example, 23 × 11 = 2 (2+3) 3 = 253.

Multiplying by 9: Multiply by 10 and subtract the original number. Example: 54 ×

2.

9 = (54 × 10) - 54 = 540 - 54 = 486.

Using the Difference of Squares: For numbers close to each other, use (a + b)(a

3.

- b) = a² - b². For example, 53 × 47 = (50 + 3)(50 - 3) = 50² - 3² = 2500 - 9 = 2491.

2. Speedy Division Techniques

Division problems can be simplified with a few tricks:

Dividing by 5: Multiply the number by 2 and then divide by 10. For instance, 235 ÷

1.

5 = (235 × 2) ÷ 10 = 470 ÷ 10 = 47.

Dividing by 9: Use the fact that dividing by 9 is the same as dividing by (10 - 1).

2.

You can estimate by dividing by 10 and adjusting accordingly.

3. Percentage Shortcuts

Percentages often trip up many, but you can handle them effortlessly with these methods:

Finding 10%, 5%, 1%: 10% of a number is just one-tenth, 5% is half of 10%, and

1.

1% is one-hundredth. Breaking down percentages into these basic units simplifies

calculations.

Calculating Any Percentage: Express the percentage as a fraction and multiply.

2.

For example, to find 12% of 250, calculate 10% + 2%: 25 + (2% of 250 = 5) = 30.

4. Square and Cube Shortcuts

Memorizing squares and cubes of numbers can speed up many problems, but there are

also tricks for calculating them on the fly:

Squaring Numbers Ending with 5: For any two-digit number ending in 5,

1.

multiply the first digit by (itself +1) and append 25. Example: 35² = 3 × 4 = 12,

append 25 → 1225.

Using Binomial Expansion: For numbers close to a base (like 50, 100), use (a ±

2.

b)² = a² ± 2ab + b². For example, 98² = (100 - 2)² = 10000 - 400 + 4 = 9604.

5. Simplifying Algebraic Expressions

Algebraic problems can be intimidating but understanding some key patterns helps:

Factoring Differences of Squares: a² - b² = (a + b)(a - b).

1.

Sum and Difference of Cubes: a³ ± b³ = (a ± b)(a² ∓ ab + b²).

2.

Using Substitution: For complex expressions, substituting variables temporarily

3.
