Answer 1

We need to subtract by adding up: $63-28=?$ we get 35

Step-by-step explanation:

We need to subtract by adding up: $63-28=?$

We will make a number line from 28 till 63 and then jump intervals to reach 63.

We will add those intervals to get the result. That result will be the subtraction of $63-28=?$

$28+2=30\\30+10=40\\40+10=50\\50+10+3=63$

So, we will add up: 2+10+10+10+3 = 35

So, $63-28=35$
