Question

Fill in the missing numbers/words.
$99+139+1=$

Answer 1

Step 1: Add the ones

Given: $99+139+1=$

First add ones $9+9+1=19$

Write $9$ under ones column and carry $1$ to tens column.

Step 2: Add the tens

Next add tens $1+9+3=13$, (Extra $1$ is carry from ones)

Write $3$ under tens column and carry $1$ to hundreds column.

Step 3: Add the hundreds

And finally add hundreds $1+1=2$, (Extra $1$ is carry from ones)

So we get,

$\mathrm{H}\mathrm{T}\mathrm{O}\mathrm{Carrr}-\mathrm{over}1113999+1239$
