# How do you simplify 16 ÷ 4 times 2 - 7 using PEMDAS?

Jul 29, 2016

$\text{ "16-:4xx2-7" " =" } 1$

#### Explanation:

Using strict application of process

P$\to$ Parenthesise (brackets)
E $\to$ Exponents (powers)
M $\to$ Multiply
D $\to$ Divide
A $\to$ Add
S $\to$ Subtract

I am advised that it is better to write this as

P-E-MD-AS as multiply and divide have the same priority. As do add and subtract.

Given:$\text{ } 16 \div 4 \times 2 - 7$

So reading left to right

$\implies \left[\left(16 \div 4\right) \times 2\right] - 7$

$\implies \left[4 \times 2\right] - 7$

$\implies 8 - 7 = 1$
