whats 9+10

Question

what 9 plus ten

 

Answer 1

 10

+ 9

-----

 

First, we look at the ones place.

 

Tens Ones

  1      0

+        9

-------------

   

 

We will add the numbers in the ones group together.

0 + 9 = 9

 

So, we'll write a 9 under the ones place.

 

Tens Ones
  1      0
+        9
-------------

          9

 

Then, we'll look at the tens place and add them together. When there isn't a number in the tens place (such as 9), we assume that it's 0.

1 + 0 = 1

 

So, we'll write a 1 under the tens place.

 

Tens Ones
  1       0
+        9
-------------
  1       9

 

Together, we have 19. 

 

So, 10 + 9 = 19!
