Answer:
If you need the answers here they are:
Question 1 answer: -2
Question 2 answer: -2
Question 3 answer: -15
And if you don't get how I got the answers, for question 1, it's pretty much 5-3 but with a negative.
question 2 the reason why I got -2 again was because a negative plus a positive always equals a negative and a negative plus a negative always equals a positive. so then because of that, the equation changes to 6-8 which equals -2.
question number 3 is just like question 2 with the parenthesis which make the equation -10-5. That makes it pretty much 10+5 but again, with a negative.
