Solve the Subtraction Problem: 63-36 Step by Step

Question

$63-36=$

00:00 Solve

00:03 We will use the distribution law

00:07 Break down 63 into 60 plus 3

00:11 Break down 36 into 30 plus 6

00:19 Negative times positive is always negative

00:33 We will use the commutative law and arrange the exercise in a convenient way to solve

00:45 We will solve one operation at a time

00:55 And this is the solution to the question

To solve the problem, first we will use the distributive property on the two numbers:

(60+3)-(30+6)

Now, we will use the substitution property to arrange the exercise in the way that is most convenient for us to solve:

60-30+3-6

It is important to pay attention that when we open the second parentheses, the minus sign moved to the two numbers inside.

30-3 =
