Question

Find an overestimate for 42 x 59 by adjusting each factor up to the next ten.

Answer 1

Explanation:

"To the next ten" means we will turn 42 into 50 and 59 into 60.

Since we are adding 8 to 42 and 1 to 60 this will not be exactly right, hence why it is an overestimate.

If, 5 * 6 = 30

Then, 50 * 60 = 3,000
