Question

4. Add one set of parentheses to make the expression equal

Answer 1

The expression that is equal to 2022 by adding a set of parentheses is 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12).

How to solve a long-expression problem?

In mathematics, parentheses are used to group a set of mathematical terms. In  a long-expression, like the one presented, using parenthesis implies:

• The terms in the parentheses are solved separately from those outside the parentheses.
• The terms in the parentheses are solved before solving those outside.
• Moving the parentheses will affect the result of the whole expression.

Based on this, the expression that equals 2022 is:

• 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12)

Let's solve it to prove this result

• 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12)

First, solve the parenthesis first by dividing and then by adding.

• 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (1 + 1)12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / 2

Now, let's solve this expression, the first step is to solve the multiplications.

• 1728 + 144 + 144 + 12/2

Now, solve the division.

• 1728 + 144 + 144 + 6

Finally, add everything.

• 1728 + 144 + 144 + 6 = 2022
