Question

How do you simplify `12 + 2 × 10^2 − 6 ÷ 2`?

Answer 1

`12+2xx10^2−6-:2=209`

Explanation:

We should use the order of operations given by PEMDAS, first starting with Parentheses (none here), then Exponents, Multiplication, Division, Addition and finally Subtraction (last two too are not applicable here).

`12+2xx10^2−6-:2` - first solving exponents

= `12+2xx100−6-:2` - now multiplication

= `12+200−6-:2` - then division

= `12+200−3` - then addition

= `212−3` - and finally subtraction

= `209`
