Multiplication and division are always done before or seperate to subtraction and addition, so we will bracket them into their own group:
7 + 14 - 3 + 5 x 2 x 2 x 2
(7 + 14 - 3) + (5 x 2 x 2 x 2)
(21 - 3) + (10 x 2 x 2)
18 + (20 x 2)
18 + 40
58
3 + 4 + 7 = 14
2/7 + 3/14 = 4/14 + 3/14 = 7/14 = 1/2
14/7 x 2 + 3 = 7
X = -24. -24+7=-17+14=-3
14
3/7 + 5/14 = 6/14 + 5/14 = 11/14
It is: 3/7+6/14 = 6/7
1/7 + 1/14 = 3/14= 1/7 + 1/14= 2/14 + 1/14= 3/14
3/7 + 3/14, we first need to get both of the denominators equaled. To do this we need to get 3/7 to something over 14. We can do this by multiplying the fraction 3/7 by 2/2. 3/7(2/2) + 3/14 6/14 + 3/14 = 9/14 So 3/7 + 3/14 = 9/14
3/6 + 5/7 = 17/14 or 13/14
Use pure substitution and work out:(2 x 3) - 7 +14 =6 - 7 +14= -1 +14= 13
4/14 or 2/7
