You see, you use PEMDAS to solve this particular equation.
PEMDAS is Parentheses, exponents, multiply/divide, addition/subtraction. (Or for Please Excuse My Dear Aunt Sally)
When using PEMDAS you solve everything in the equation in that order, so your equation was 11+5x2+8x1=
So you go through each step of PEMDAS.
Parentheses? Nope. check that off
Exponents? Nope check that off
Multiply/Divide? Yes! (To clarify, multiply and divide are two separate thing combined for one step. So you just solve whatever comes first)
Addition/Subtraction? Yes!
If it's easier, it's okay to separate what you're working on at hand from the rest of the equation momentarily.
11+ (5x2) + (8x1) =
11 + 10 + 8 =
Now we're at the final stage of PEMDAS. You just add or subtract! (depending on whether the number is negative or positive)
11 + 10 + 8 =
(11+10) +8=
21 + 8 = 29
That's all there is to it! With practice it gets a LOT easier. I hope this helped!
