Abe correctly rounded all of the values to the nearest ten to
estimate and then used a calculator to determine the exact
value of the expression.
542 - 360 = (472 - 442)
Which statements are true about Abe's estimated result
and calculated result for this expression? Check all that
apply
Abe's exact answer is 530.
Abe's estimated answer is 528.
0 Abe's exact answer is 528,
Abe shouldn't use a calculator on the first step (472-
