7-6=1, 1+5=6. 6 is your answer.
-18
It is 5.
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 + 5 - 90 + 76 = -5
Using BIDMAS/PEMDAS, the question is x + 5/2 = 20 So x = 20 - 5/2 = 171/2
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)
5 + 2 x 4 + 1 =PEMDAS (parenthesis, exponents, multiplication, division, addition, subtraction)5 + 8 + 1 = 14
The answer is 76. 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.
(-15) + 91 = 76 [ -5 times (-15) ] + 1 = 76 (-1,140) / (-15) = 76
Pemdas says that addition and subtraction can be done in any order, so it doesn't matter. 15 - 5 = 10 10 + 9 = 19 19 - 2 = 17 The answer is 17. Pemdas- Parentheses, Exponents, Multiplication/Division, and Addition/subtraction. The slashes mean that those two can be done in any order, and you will get the same answer/
23. You must use PEMDAS Parentheses () Exponents * Multiplication X Addition + Subtraction - So... 5 + 3 x 6 5 + 18 23
Remember PEMDAS or BEDMAS or BEMDAS (they all mean the same thing)7+25/57+512
