Answer:
The answer is 71
Step-by-step explanation:
** Follow the PEMDAS (Order Of Operations)
1. Multiply and divide from left to right
9(-4) = -36
**** This leaves you with 18-(-36)-3+10*2
2. Multiply and divide from left to right
10*2=20
**** This leaves you with 18-(-36)-3+20
3. Add and subtract from left to right
18-(-36)-3+20=71
****** And your final answer is 71!
Answer:
The answer is 50.
Step-by-step explanation:
We should use the "BODMAS" rule in solving problems like this.
If an expression contains B-(brackets), we have to first solve the bracket followed by O-(orders or power), then D-(division), M-(Multiplication, A-(addition) and S-(subtraction).
a. 18 - 9 x (-4) ÷ 3 + 10 x 2
= 18 - 9 x (-4/3) + 10 x 2
= 18 - (-12) + 10 x 2
= 18 - (-12) + 20
= 18 + 12 + 20
= 50
[18 - 9 x (-4) ÷ 3 + 10 x 2] = 50
