7-6=1, 1+5=6. 6 is your answer.
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.
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
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
the equation would be (according to pemdas or order of operations) is 43-(25/5)+2 43-(5)+2 43-3 40
For the problem 5+6*2+3x-7*3+6x , you would use PEMDAS to find the order of whichparts to do first. PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. So first, you should do the multiplication in this one since theres no parenthesis or exponents. After doing the multiplication, it'd look like 5+12+3x-21+6x. Now you can simply add and subtract to solve the rest. The final answer will be 9x-4.
