Question

Evaluate the expression 8 - 3 × 2 + 5

Answer 1

7

Explanation:

Simplify by following order of operations known as PEMDAS.

P - parenthesis

E - exponent

M - multiply

D - divide

A - add

S - subtract

* Keep in mind that the M & D go together such as the A & S. Simply meaning which ever comes first do it.

Now, first we are given the problem 8 - 3 x 2 + 5 and according to our PEMDAS method we first carry out M (multiplication). Which gives us 8 - 6 + 5. Now we have an addition and subtraction problem in this scenario, however first we are given 8 - 6 (keep in mind read the expression or equation left to right when solving these) so we get 2 + 5 now given our simplification. Thus providing you with the answer of 7.

Answer 2

Explanation:

without any brackets to tell us otherwise, remember, multiplications and divisions before any additions or subtractions.

so,

8 - 3×2 + 5 = 8 - 6 + 5 = 7
