now you do the Order of Operations
P anything in ()
E exponents (²)
M multiplication
D division
A addition
S subtraction
first do (-4-1)²
-5²= -5* -5= 25
now we have... 25+2(1) - 7(-4)
now do 2*1= 2 also do 7 * (-4)= -28
now we have 25+2-(-28)
because there is that -(-28) just make it a +28
now do 25+2+28
27+28
