5 times 2-3 plus 4times 8 plus 1?

Answer 1

Judging by the way you write your question, the equation above probably look like this: 5 * (2 - 3) + 4 * 8 + 1

Operations inside a parenthesis goes first

5 * (2 - 3) + 4 * 8 + 1

MDAS rule:

5 * -1 + 4 * 8 + 1

-5 + 32 + 1

-5 + 33

28

or if you mean 5(2 -3) + 4(8 + 1) then,

5(2 -3) + 4(8 + 1)

5(-1) + 4(9)

-5 + 36

31
