Answer: [tex]=-42[/tex]
Step-by-step explanation:
Given the following expression:
[tex]6 - 2(-1) + 1-51[/tex]
It is important to remember the multiplication of signs in order to evaluate it:
[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-[/tex]
Then, the first step is to solve the multiplication in the expression:
[tex]6 - 2(-1) + 1-51=6+2 + 1-51[/tex]
And finally, adding the numbers, you get:
[tex]=-42[/tex]
