P.E.M.D.A.S. Parenthesis, Exponents, Multiplication/Division, then addition/subtraction.

Answer 4

@JillyCraft64 have you done the first step?

Answer 5

\(\dfrac{24 - 4 * 2}{12 \div 4 + 1}\)

First multiply 4 and 2 in the numerator:

4 * 2 = 8

\(\dfrac{24 - 8}{12 \div 4 + 1}\)

Now divide 12 and 4 in the denominator:

12 / 4 = 3

\(\dfrac{24 - 8}{3 + 1}\)

Now subtract 24 and 8 in the numerator:

24 - 8 = 16

\(\dfrac{16}{3 + 1}\)

Add 3 and 1 in the denominator:

3 + 1 = 4

\(\dfrac{16}{4}\)

Now divide 16 and 4:

16 / 4 = 4

\(4\)
