Yes, that's correct.
This is what it means:- 2(-3-5)-(2 + 2)
And that is 2 x (-3-5) - (2 +2) = 2 x (-8) -(4) = -16 - 4 = -20

(24/2)*8-3*(6-2)+1 = (12*8)-(3*4)+1 = 85
2-(-1)= 2+1= 3 When a parenthesis is preceded by a minus sign, remove the parentheses and the minus sign before the parentheses and change the sign of each term within the parentheses. When a parenthesis (-1) is preceded by a minus sign, -(-1) remove the parentheses ( ) and the - sign before the parentheses and change the sign of each term -1 within the parentheses +1
(5 - 3)(x + 2) = 5x + 10 - 3x - 6 = 2x + 4
assuming that there are no parentheses around the (7-1) then it should be 10.7
(43 - 19) + (16 - 14)(4)= 24 + (2)(4)= 24 + 8= 32

(5 - 3)(x + 2) = 5x + 10 - 3x - 6 = 2x + 4
As written, those are the same. For that sentence to equal 3, we need to use parentheses. (8 + 4) divided by 2 minus (1 x 3)
If something plus and minus something else make two then the initial value must be 2.
assuming that there are no parentheses around the (7-1) then it should be 10.7
A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9
3 X 2 + 10 - 3 ( 8 - 6 ) 3 X 2 + 10 - 3 ( 2 ) Parentheses first 6 + 10 - 6 There are no exponents, so multiplication and division next 10 Addition and subtraction last
That would depend on the plus or minus value of 2 which has not been given.
3(x+2) = x -18 3x+6 = x -18 3x -x = -18 -6 2x = -24 x = -12
