Hi there!
For this, we would be using PEMDAS:
Parentheses
Exponents
Multiplication (from left to right)
Division (from left to right)
Addition (from left to right)
Subtraction (from left to right)
1.Multiply all terms:
[tex]3[/tex]·[tex]4[/tex]·[tex]5[/tex][tex]-8[/tex]·[tex]9[/tex]·[tex]10[/tex]·[tex]11=60[/tex]
2.Multiply the terms again:
[tex]60-8[/tex]·[tex]9[/tex]·[tex]10[/tex]·[tex]11=[/tex][tex]60-7920[/tex]
3.Subtract the terms:
[tex]60-7920=-7860[/tex]
Therefore, the answer would be -7860.
