2. Learn Mental Math Tricks for Simple Operations

Now that you've got your arithmetic basics down pat, it's time to start learning some mental math magic! Let's explore some strategies that will help you perform calculations more quickly and easily in your head.

Rounding Numbers

One of the most useful mental math tricks is rounding numbers to make them easier to work with. For example, if you need to add 398 + 237, you could round 398 up to 400 and 237 down to 235. Now you're dealing with 400 + 235, which is much easier to calculate mentally. Just remember to subtract 2 from your final answer to account for the rounding.

Number Splitting

Another handy technique is splitting numbers into more manageable parts. Let's say you need to multiply 16 x 25. You could split this into (16 x 20) + (16 x 5). 16 x 20 is 320, and 16 x 5 is 80. Add these together, and you get 400.

Practice Makes Perfect

Multiplication Tricks

Here are a few tricks to get you started:

• Multiplying by 11: To multiply a two-digit number by 11, add the two digits and place the result between them. For example, 45 x 11 = 495 (4 + 5 = 9, so place 9 between 4 and 5).
• Squaring numbers ending in 5: To square a number ending in 5, multiply the tens digit by the next whole number and append 25. For example, 35² = (3 x 4) = 12, so 35² = 1225.

Division Shortcuts

Division can be trickier, but here are some tips:

• Dividing by 5: To divide by 5, multiply by 2 and then divide by 10. For example, 85 ÷ 5 = (85 x 2) ÷ 10 = 170 ÷ 10 = 17.
• Recognizing divisibility: Learn divisibility rules to quickly identify if a number is divisible by 2, 3, 4, 5, 6, 9, or 10.

The Power of Tables

While shortcuts are great, there's no substitute for knowing your multiplication tables by heart. Extend your knowledge beyond the standard 12 x 12 table. Try to memorize squares up to 20² and common multiplications like 25 x 25 or 15 x 15. This knowledge will serve as building blocks for more complex calculations.
