# How do you simplify the expression 6(times) 7 - 3(4 + 1) ?

Jul 29, 2016

Use the PEMDAS method.

#### Explanation:

PEMDAS stands for:

Parentheses
Exponents
Multiplication
Division
Subtraction

Let's go through each:

Parentheses

We have one, $\left(4 + 1\right)$, which equals $5$. This gives us $6 \cdot 7 - 3 \cdot 5$.

Exponents

None.

Multiplication

We have two, 67 and 35. $6 \cdot 7 = 42$ and $3 \cdot 5 = 15$. This gives us 42-15.

From here, all we need to do is subtract 15 from 42, which gives us $27$.
