This game is about estimation. I rounded off numbers to the nearest ten. This is my strategy.I rounded 456 to 500 because the 456 is closer to 500 not 400.
The I made the 67 a 70 because 67 is closer to 70 than 60.
So I used a strategy of 500 x 70 = 35 000
It was challenge but I managed to get it right. The correct answer is C. Next, I want to learn how to do it faster.
