This question i am stuck on for like 2 days. So what i have to do is try to work this question out but provide working out every step i get an answer.
-3 x 5 + 6 (divide) -3 x -2 - 4 + (square root)25 - (4 - 2 x 3)
You have to look at the question carefully to see if a number is negative or a minus sign. Please please help me and provide me with working out and it'll make my day. thanks (:
Key :
(Square root) = square root
(divide) = divide
-3 x 5 + 6 (divide) -3 x -2 - 4 + (square root)25 - (4 - 2 x 3)

-3 * 5 + 6 / -3 * -2 - 4 + √25 - (4 - 2 * 3)
-15 + -2 * -2 - 4 + 5 - (-2)
-15 + 4 - 4 + 5 + 2
-8
-15 + -2 * -2 - 4 + 5 - (-2)
-15 + 4 - 4 + 5 + 2

5 x 3 is 15, the negative makes it minus 15 (Remember, positive times positive or negative times negative is positive, negative and positive makes it negative), plus 6 gives minus 9, which becomes the top number.
Now for the bottom number. 3 x 2 is 6, the two negatives make it positive. Less 4 is 2, plus 5 (the square root of 25) is 7. Less 4 -2 (2) x 3 which is 6
So, you have minus 9 divided by 6, which will give you a negative number, of minus 1.5
Now for the bottom number. 3 x 2 is 6, the two negatives make it positive. Less 4 is 2, plus 5 (the square root of 25) is 7. Less 4 -2 (2) x 3 which is 6
So, you have minus 9 divided by 6, which will give you a negative number, of minus 1.5

the first step would be to properly write out the equation.
then you need to follow the order of operations, commonly remembered as PEMDAS-parentheses, exponents, multiplication/division from left to right, addition/subtraction from left to right
-3 * 5 + 6
-------------- + √25 - (4-2*3) write out eqn
-3*-2 -4
-3 * 5 + 6
-------------- + √25 - (-2) parentheses
-3*-2 -4
-15+6
--------- + 5 + 2 simplify everything
6 - 4
-9
--- + 5 + 2 divide
2
-4.5 + 5 + 2 add/subtract from left to right
.5 +2 add/subtract
1.5 answer

PEMDAS
-3*5+6/-3*-2-4+√25-(4-2*3)
Parenthesis first
4-2*3
multiply first
4-6
then subtract
-2
so
-3*5+6/-3*-2-4+√25-(-2)
Exponent next
√25 = 5
so
-3*5+6/-3*-2-4+5-(-2)
Multiply and Divide next, left to right
-3*5 = -15
6/-3*-2 = -2*-2 = 4
so
-15+4-4+5-(-2)
Add and Subtract last, again left to right
-15+4 = -11
-11-4 = -15
-15+5 = -10
-10-(-2) = -10+2 = -8
so
-3*5+6/-3*-2-4+√25-(4-2*3) = -8
-3*5+6/-3*-2-4+√25-(4-2*3)
Parenthesis first
4-2*3
multiply first
4-6
then subtract
-2
so
-3*5+6/-3*-2-4+√25-(-2)
Exponent next
√25 = 5
so
-3*5+6/-3*-2-4+5-(-2)
Multiply and Divide next, left to right
-3*5 = -15
6/-3*-2 = -2*-2 = 4
so
-15+4-4+5-(-2)
Add and Subtract last, again left to right
-15+4 = -11
-11-4 = -15
-15+5 = -10
-10-(-2) = -10+2 = -8
so
-3*5+6/-3*-2-4+√25-(4-2*3) = -8
-
[-3 x (5 + 6) / -3 x (-2 - 4)] + [sqrt(25) - (4 - 2 x 3)]
= -3*11 / 18] + [5 -(4-6)] = -11/6 + 5 +2
= -11/6 + 7 = [-11 + 42] / 6 = 31 / 6 >============< ANSWER
= -3*11 / 18] + [5 -(4-6)] = -11/6 + 5 +2
= -11/6 + 7 = [-11 + 42] / 6 = 31 / 6 >============< ANSWER

could you make the notation clearer is it 6/(-3) or 6/(-3 x -2 - 4 + (square root)25 - (4 - 2 x 3))
