My Math Strategy!

W.A.L.T Multiply using tidy numbers, rounding and compensating.

Today I have to do an Example and Explain how to do my Math strategy. I drew out the how I do it in my book and took a photo of it.

Here is my Strategy!
How I done it...
My Problem was 68x98. I added 2 to make it 70, and then I times it by 98. The answer was 6860. Then I took the two that I added to make the 68 70, and times that by 98. That equals 196. Then I done 6860-196 and that was 6664. So the answer is 6664.
