Explanation: This question's it's about the order of operations. It stands for p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right. (PEMDAS)
1. -4(3-1)+2
Do parenthesis first.
[tex](3-1)=2[/tex]
[tex]-4*2+2[/tex]
Then do multiply left to right.
[tex]-4*2=-8[/tex]
Add left to right.
[tex]-8+2[/tex]
[tex]8-2=6[/tex]
*Answer should be have negative sign.*
Answer: → [tex]\boxed{=-6}[/tex]

2. 3⋅[(30−8)÷2+2]
Do parenthesis first.
[tex](30-8)=22[/tex]
[tex]22/2+2[/tex]
Then divide left to right.
[tex]22/2=11[/tex]
Add left to right.
[tex]11+2=13[/tex]
Multiply left to right.
[tex]3*13=39[/tex]
*Answer should be have positive sign.*
Answer: → [tex]\boxed{=39}[/tex]

3. 14(1-23)2+13
Do parenthesis first.
[tex](1-23)=-22[/tex]
[tex]14(-22)*2+13[/tex]
Then, you multiply left to right.
[tex]14(-22)=-308[/tex]
[tex]-308*2=-616[/tex]
Add/subtract left to right.
[tex]-616+13[/tex]
[tex]616-13=603[/tex]
*The answer must be have a negative sign*
Answer: → [tex]\boxed{=-603}[/tex]
