# How do you insert parentheses to make 6xx7-3xx4+1=27 true?

Apr 10, 2018

$6 \times 7 - 3 \times \textcolor{b l u e}{\left(4 + 1\right)} = 27$

#### Explanation:

We got: $6 \times 7 - 3 \times 4 + 1 = 27$

So, in order to make this true, we insert parenthesis here:

$6 \times 7 - 3 \times \textcolor{b l u e}{\left(4 + 1\right)} = 27$

$6 \times 7 - 3 \times 5 = 27$

$42 - 15 = 27$

$27 = 27$

Obviously this is true, so we need to insert the brackets at the $4 + 1$ part.
