Answer:
10
Step-by-step explanation:
PEMDAS: Parenthesis, Exponents Multiplication, Division, Addition, Subtraction
You can leave the parenthesis on the 2 but they are just there to show that 5 is being multiplied by 2. So you can eliminate parenthesis. There are no exponents so move on to multiplication. 5 x 2 = 10. So now the equation should look like this:
35 - 10 + 15 = ?
OK, you can now move onto Addition, because there is no division in this equation. 10 + 15 = 25. So now your equation would look like this:
35 - 25 = ?
And last but not least you have Subtraction. 35 - 25 = 10.
So the answer is 10. :)
