How is place value used to model and find products when multiplying 2 digit numbers?
Aleksandr-060686 [28]

Answer:

1 x 4=4 (Both numbers are in the ones place, so their value are ones.)

Step-by-step explanation

In order to use place value to multiply, we use the distributive property to break apart each place. Always begin with the ones place. We can break apart a 2-digit by 1-digit number into 2 simpler problems. 1 x 4=4 (Both numbers are in the ones place, so their value are ones.)
