Question

How much is 79 tens + 10 tens =

Answer 1

79+10=89 tens or 890

Answer 2

890 or 89 tens

Step-by-step explanation:

Tens is numerically converted into 10

This means that:

79 tens = 79 * 10 = 790

10 tens = 10 * 10 = 100

Now, we can simply add the two numbers:

790 + 100 = 890

If we want to write in as "tens", we will simply remove 10 as follows:

890 =
`(890)/(10)` = 89 tens

Hope this helps :)
