Toes♀Glitch in the matrix
TheOneWithTheHairDon’t use the one on the left.
otacon239Nope. It’s PEMDAS at work.
8/2(2+2) 8/2(4) - Parentheses 8/8 - Multiplication 1 - Division
Modern phone apps seem to be notorious for getting order of operations wrong. I’ve never had this issue with a dedicated calculator.
Actively wrong.
PE(MD)(AS).
Parenthesis comes first, do everything in each of them as though they were a whole equation to themselves.
8/2(2+2) = 8/2(4)
Then you do your exponents. The equation doesn’t have any, so we can go ahead and skip those.
Multiplication and division are the same operation, just flipped around, so you go left to right and do those as you come across them. A number next to a parenthesis means multiplication, so to simplify:
8/2(4) = 8/2*4
8/24 = 44
4*4 = 16
Addition and subtraction don’t have any weird effects on the outcomes of each other, so you go left to right and do them as they come up. This equation has no more addition or subtraction to do, so we can consider what we have left our answer.
Therefore: 8/2(2+2)=16
This is straight from the textbook. You are wrong, and so are your purpose-built calculators.

You haven’t finished Brackets yet! The next step is…
8/(2x4)=8/8
This is straight from the textbook
Not any textbook I’ve seen. Screenshot? Here’s some actual textbooks

@[email protected] @[email protected] both got the correct answer of 1 - well done! Let's look at the correct working out, then delve into where people go wrong with their #Maths #math 8/2(1+3) =8/(2*1+2*3) =8/(2+6) =8/8 =1 Also acceptable is... 8/2(1+3) =8/2(4) =8/(2*4) =8/8 =1 If you've seen someone say that it's ambiguous, it isn't - we shall see in coming weeks that #MathsIsNeverAmbiguous they have simply forgotten one or more #Mathematics rules First, #DontForgetDistribution the Distributive Law...
Child, this thread is literally four months old. Get a life.
Yeah, didn’t think that came from any textbook.
