Question

7*8-(5*6-12):3-49:(7*7)

Answer 1

7*8-(5*6-12):3-49:(7*7)=56-(30-12):3-49:49=56-18:3-1=56-6-1=50-1=49

Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's break down your expression step by step:

1. First, calculate inside the parentheses: 5 * 6 = 30

2. Next, subtract the result from step 1 from 12: 12 - 30 = -18

3. Now, move on to the division: -18 / 3 = -6

4. Calculate 7 * 8: 7 * 8 = 56

5. Calculate 7 * 7: 7 * 7 = 49

6. Finally, perform the remaining operations from left to right: 56 - (-6) - 49

To subtract a negative number, you can add its positive counterpart: 56 + 6 - 49

Now, perform the addition and subtraction from left to right: 62 - 49 = 13

So, the final result of the expression is 13.
