I have a math problem with multiplication and subtraction, which should I do first?
multiplication
-24 + 7
17
(1/3) divide (-7/8)
-8/21
-2
Ex. 8 + 7 - (-3) + 12
Work from Left to Right (in this example, add, then subtract, then add).
25 - (-4) =
29
1/3 times 3/4
3/12 or 1/4
(-56) / (-7) = n
n = 8
What step would I do first? Second? Third?
1st: grouping symbols - subtract what's in the ( )
2nd: Multiply
3rd: Add
- 14 - 5.2
-19.2
-5.5 + 2.8
-2.7
n / (-7) = 6
n = -42
Solve:
-2 + (-4) x 8 - 14
-48
100 + (-25) + (-25) - (-50)
100
-3.5 x 2 + (-10)
-17
