Multiplying
Multiplying is a way of adding a number many times. You use the " * " sign for the multiplying operation. If you have 4 apple trees and every tree has 25 apples, you have 100 apples. This is 4 * 25 = 100 or 25 + 25 + 25 + 25 = 100 in the signs of Math. The first way is shorter and easier to use.
Multiplying 25 by 4 is the same as adding 25, 4 times or adding 4, 25 times.
Order is not important when multiplying. 2 * 3 is the same as 3 * 2.
Dividing
Dividing is the opposite of multiplying. You use the " ÷ " sign for the dividing operation. If 3 friends take an equal part of a bag of 12 apples, every friend gets 4 apples. This is 12 ÷ 3 = 4 in the signs of Math.
Order is important when dividing. 3 ÷ 2 is not the same as 2 ÷ 3.
