Question

13. Multiply. 5 · 37

Answer 1

Multiply 7 and 5 to get 35 (use memorization, fingers, or your multiplication table). Write down the 5 (from 35) and write a small 3 down that will signify that you're going to use that as a carry.


Now multiply 3 and 5 to get 15. Now add that last carry of 3 to 15 to get 18


Now write the 18 just to the left of that first 5 you wrote down to get 185


Visually, you might see it as this


.37
...5
