Question

What is the answer to this problem

Answer 1

5 x 70 = 5 x 7 tens
5 x 70 = 35 tens = 350

Answer 2

350

Explanation:

The completed problem is

`5 * 70=5* 7 \ tens.\\5 * 70=35 \ tens=350`

Basically, the process is only about separating tens from units, so basically "tens" represents the zero, that's why we only multiply 5 and 7 digits, and add the zero at the end. It's an easier way to multiply tens.
