Wikijunior:Introduction to Mathematics/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 mathematics. 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.
