Calculate the Product: 18 × 69 Step-by-Step

To make it easier for us to solve, let's break down 12 and 19 into more convenient numbers, preferably round ones.

We get:

$(20-2)\times(70-1)=$

We'll use the distributive property to solve.

First, we'll multiply the first term in the left parentheses by the first term in the right parentheses.

We'll multiply the first term in the left parentheses by the second term in the right parentheses.

We'll multiply the second term in the left parentheses by the first term in the right parentheses.

We'll multiply the second term in the left parentheses by the second term in the right parentheses.

We get:

$(20\times70)-(20\times1)-(2\times70)-(2\times-1)=$

Let's solve what's in the parentheses and we get:

$1,400-20-140+2=$

We'll use the associative property and first solve:

$20-140=160$

Now we get:

$1,400-160+2=$

Let's solve from left to right:

$1,400-160=1,240$

$1,240+2=1,242$
