Answer 1

`\huge\boxed{\bf\:62}`

Explanation:

`(9*7) + 7 - 8 = ?`

We can solve this by using the PEMDAS concept where,

• P = Parentheses
• E = Exponents
• M = Multiplication
• D = Division
• A = Addition
• S = Subtraction

So, to solve this, we need to solve the numbers in the parentheses by doing the requested operation (here it is, mutiplucation).

`(9*7) + 7 - 8\\= (63) + 7 - 8`

Now, by looking at the PEMDAS rule, we can see that the next step is addition (as, we don't have to divide in this question).

`(63) + 7 - 8\\= 63 + 7 - 8\\= 70 - 8`

Now, subtract 8 from 70 .

`70 - 8\\= \boxed{\bf\:62}`
