Using pemdas, the subtraction and addition happen at the same time. If there are no parenthesis, then you just go from right to left. 8-5=3 3+4=7 So 7 is your answer.
- 4 x 2 - 8 = 0 Using PEMDAS -8 - 8 = 0 Answer = - 16
2 + 2
5 + 2 x 4 + 1 =PEMDAS (parenthesis, exponents, multiplication, division, addition, subtraction)5 + 8 + 1 = 14
Using a word problem using 24 by PEMDAS is simple. You would write 24 times 20 divided 4.
Nine. Using PEMDAS, you start with 12/4, which is three. Then the problem is 9-3+3, which is basically just 9. Nine.
2 plus 2 squared is 2+2^2 in equation form. By PEMDAS (or Please Excuse My Dear Aunt Sally), you would have to do 2^2 (2 squared) first. 2^2 is 4. Then, you add 2+4, which is 6. The final answer is 6.
23 - (Parenthesis, Exponents, Division, Multiplication, Addition, Subtraction) The answer would be 23. (do the multiplication first) 4 x 5. (20) then add the three. (20 plus 3 = 23)
PEMDAS says to divide first then addSo64/4=1616+7=23
The answer is 26. Simply add up all of the numbers arithmetically like you would for two plus two. To make sure the answer is correct, check your work using a calculator.
(xy - 4) ^2 + (2x+2y)^2
My original answer was wrong and was corrected by Eric Barnes.Remember BIDMAS (UK) or PEMDAS (US) which sets out the order of operations.These stand forBrackets or ParenthesesIndex or ExponentDivision and MultiplicationAddition and Subtraction.So 6(-3) + 12/(-2) + 4= -18 + (-6) + 4 = -8 + 4 = -20.
