For example, the average of 18 and 14 is 16. To multiply two numbers, first find their average (the number exactly between them).Memorize the squares from 1 to 20 (or higher, if you're ambitious).With a little extra work, you can use these squares to find the answer to other problems: X Research source But for larger numbers, instead of trying to memorize hundreds of answers, it's more efficient to memorize just the squares instead (each number times itself). Memorizing your multiplication tables from 1 to 9 makes single-digit multiplication automatic. Squares charts give you a new way to multiply. Now multiply 25 by 20 (instead of ten) to get 500, and add 1 x 4 = 4 to get 504. X Research source For example, for 21 x 24, you start by adding 21 + 4 to get 25.

Next, subtract ten from both sides and multiply the results: 3 x 5 = 15. A game for two players or teams testing their speedy reactions to mental arithmetic questions.Multiply your answer by ten: 18 x 10 = 180.Subtract 10 from the second number, then add your answer to the first: 15 - 10 = 5, and 13 + 5 = 18. Let's look at numbers close to 10, like 13 x 15.This is easiest when multiplying two numbers that are both in the range of 11 to 19, but you can learn to use it for other problems: X Research source It can be a little tricky to remember at first, but once you have it down it can make multiplication much faster.
