a = 7 a = 7-6 = 1 (3*(1-5)+12) (3*(-4)+12) ((-12)+12) = 0

If you are unsure how the code works or what the calculation does, you can print out the steps with console.log(). Good night ;)

From your profile it looks like you completed the Javascript course... Did you try to run this code and print the intermediate steps? 7 – 6 = 1 3*(1–5) + 12= 3*(-4) + 12 = 0 Yaroslav Vernigora thanks, edited!

its okay, thats what the community is for. all of us are once wrong. even Lisa messed up a little with the answer. it can affect later time. its about half past one in the night on my watch. I think that Germany has something like that...

a = 7- 6 = 1 [3*(1-5) + 12] You solve inner bracket first i.e () [3*(-4) + 12] Then multiplication [-12 + 12] 0 It is correct check on Bodmas rule Bracket Of Division Multiplication Addition Substraction

Mirielle no I were confused in brackets, I were adding all the values first which is equal to 8 than multiply, that's why.

a = 7 a = 7-6 = 1 For console. Log.... (3*(1-5)+12) (3*(-4)+12) ((-12)+12) = 0
