SOLUTION:
Since we have no parentheses nor exponents, we go multiplication and division.
First, we divide 7 by 7 which gives us 1. Then, we tackle the multiplication: 7 times 7 = 49.
You’re doing great!
Our next step is to substitute these results into an equation:
Now we have 7 + 1 + 49 – 7 = ?
It means that there are only the addition and subtraction left. Let’s do it from left to right:
7+1 = 8
8+49 = 57
And finally, 57 – 7 = 50!
