Here is one of my equation that I haven't worked out (8x29=).
Let's use place value to work this stategy out and then we’ll use compensation.
First you times 8 to a tidy number in the stategy which is 20 then you plus 8 times 9. After that you add them all together and you will get the answer and the answer is 232. Here do it like this.
(8x20=160)+(8x9=72) then add them all together and the answer is 232.
Next strategy we can use is competsation.
First you times 8 to a tidy number which is 30. Then take away 8 times 1. When you finish you add them up and the answer is there.
Here like this.
8x30=240 take away 8x1=232
