Answer:
a. 49
Step-by-step explanation:
so, basically turn the equation around! -15+64. because -15 is in parentheses, we know that it is negative, but another way you can do it is to take away the addition symbol and just use the negative as a subtraction one. so you could do 64-15 and you get 49. for b it's a little different, two negative cancel each other out so because there's a subtraction sign after 18 and there's a negative sign before 55 you can see that to simplify the equation it would be -18+55 or again 55-18. for c I think that one is pretty simple, just do 92-86 (I don't know if you see the pattern yet but most times you can just flip it around.) and for d you can do 17 plus 44 and then make the solution negative. I hope this helped a little!!
