Multiplication

Multiplication is repeated addition

What this means is that multiplication is a faster way to add

If we have 7 bags of flowers, and there are 34 flowers in each bag, its easier to multiply than to add 34, 7 times.

Especially since we are getting into bigger numbers this year

When we multiply by 10's, 100's and 1,000's all we are doing is adding zeros to the end of the numbers. Look at the pattern

2x10=20

2x100=200

2x1000=2,000

Notice how we added zeros to the end of the answer

Any time we have zero's in our bottom number, we can just add the zeros

For example 7x200

7x2=14

Add two zeros to the end because that's how many zeros are in 100

So our answer is 1,400

try one on your own: 5X5,000

what about 23x100?
