1) Describe a real-life situation that could be represented by the expression 3 + 2 x 6.
2) Dina calculated each of the following mentally:
a. 49 x 51 + 49 x 49 = 4900
b. 98 x 37 +2x 37 = 3700
C. 99 x 37 + 37= 3700
Explain how she performed the calculations and why her method works. Then give three similar calculations
based on the same approach and find the answers mentally.
3) A student asks how you can find the quotient and the remainder in a division problem like 95 -30 using a
calculator that can perform only the four basic operations, How do you respond?
