-125
BEDMAS, like its counterpart BODMAS, is used as an acronym which gives the order of precedence of certain mathematical operations. It stands for:
B - Brackets
E - Exponentials
D - Division
M - Multiplication
A - Addition
S - Subtraction
This specifies the order in which arithmetic operations take place. That is brackets expressions should be solved first, followed by exponentials, then division and so on.
Using BEDMAS, let's solve 9+10-8(9)x2
Follow these steps;
i. Solve the bracket first.
9+10-72x2
ii. Next solve the multiplication
9+10-144
iii. Then solve the addition
19-144
iv. Now, the subtraction
-125
Therefore;
9+10-8(9)x2 = -125 using bedmas
