This is a question my teacher gave me and there are no parenthesis or whatever you might think it needs. It's 20 divided by 4 minus 5 plus 12. I think the answer is -12, but I'm not sure. PLEASE HELP!!!
If it's
(20/4) - 5 + 12, that is
5 - 5 + 12 = +12.
It's not solvable as its stated.
20/4 = 5
5-5 = 0
0 + 12 = 12
OR
20/(4-5) = -20
-20 + 12 = -8
OR
You get the idea --
To solve the mathematical expression, 20 divided by 4 minus 5 plus 12, you need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to ensure the correct answer.
1. Start by performing the division operation: 20 divided by 4 equals 5.
Equation becomes: 5 minus 5 plus 12.
2. Next, perform the subtraction: 5 minus 5 equals 0.
Equation becomes: 0 plus 12.
3. Finally, perform the addition: 0 plus 12 equals 12.
Therefore, the correct answer to the expression 20 divided by 4 minus 5 plus 12 is 12, not -12.
