Math question for Ruby

Question

What is the output of 5-2*3+3?
I think, it is 4, but the answer is 2, I don't understand

Answer 1

5-2*3+3
first the 2*3 will execute which will be 6
now we've got:
5-6+3
5-6 is -1
-1+3 is 2
easy ^^

Answer 2

That's because of the highest priority of the multiplication operator... If you're not sure, use parenthesis to get the expected result ^^

Answer 3

2 * 3 = 6
5 - 6 = -1
-1 + 3 = 2

Answer 4

@Greg Oboroceanu:
Addition and substraction are done from left to right priority ^^

Answer 5

certainly 2 is the answer

Answer 6

ohhh yeah thank you!!! :)

Answer 7

The answer is 2

Answer 8

5-2*3+3
=5-(2*3)+3 (multiply is priorité to make)
=5-6+3 (they group the positive numbers =5+3-6 and the negaitve number)
=8-6 (then, thay execute them)
=2. ( finally, answers is 2)

Answer 9

* and / are operated first

Answer 10

=5-2*3+3
=5-6+3 {multiply 2 and 3}
=-1+3
=2
So, 2 is the answer.

Answer 11

the Answer will be 2 positive

Answer 12

yeah it's 2 as firstly -2*3= -6 and then 5+3=8
so basically -6+8=2

Answer 13

please help me clarify why is the addition operator not evaluated first?
=5-(2*3)+3
=5-(6+3)
=5-9
=-4??

Answer 14

BODMAS should be applied I think so...

Answer 15

considering the given calculation, it follows the arithmetic operation precedence. first you need to check for multiplication or division or the other way(whichever comes first from left to right), then proceed with addition or subtraction or the other way(whichever comes first from left to right).
