Hi Kim,

There is a convention concerning the order in which we do arithmetic operations.
Some people remember it as BEDMAS.

B: Perform any operations inside brackets
E: Perform any exponentiation or powers
D: Division
M: Multiplication
A: Addition
S: Subtraction

For example 3 x 5 + (6 ÷ 3) - 4

First inside the Brackets

3 x 5 + (6 ÷ 3) - 4
= 3 x 5 + (2) - 4
= 3 x 5 + 2 - 4

No Exponents and no more Division so Multiplication is next

3 x 5 + (6 ÷ 3) - 4
= 3 x 5 + (2) - 4
= 3 x 5 + 2 - 4
= 15 + 2 - 4

Addition

3 x 5 + (6 ÷ 3) - 4
= 3 x 5 + (2) - 4
= 3 x 5 + 2 - 4
= 15 + 2 - 4
= 17 - 4

and finally Subtraction

3 x 5 + (6 ÷ 3) - 4
= 3 x 5 + (2) - 4
= 3 x 5 + 2 - 4
= 15 + 2 - 4
= 17 - 4
= 13.

Now try your problem,
Penny
