Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

But 2 + 5 + 8 - 5 is 16 - 5 which is 11

[–] untorquer@lemmy.world 0 points 2 weeks ago (2 children)

Gotta distribute:

2+(8+5)-(5+5)

2+13-0

15

Gotta distribute:

Yes, but...

2+(8+5)-(5+5)

You didn't. 2+5(8-5)=2+(5x8-5x5)

You're trolling, but no, if you distribute you get the same result:

2 + 5(8 - 5) =

2 + (5 × 8) + (5 × -5) =

2 + (40) + (-25) =

2 + 40  - 25 = 2 + 15 = 17

[–] SmartmanApps@programming.dev 0 points 3 days ago

2 + 5(8 - 5) = 2 + (5 × 8) + (5 × -5)

Nope. 2 + 5(8 - 5) = 2 + (5 × 8 - 5 ×5) . a(b+c)=(ab+ac)

Parentheses first then Division or Multiplication then add or subtract. PEDMAS

8-5= 3

3*5=15

15+2=17

[–] SmartmanApps@programming.dev 0 points 3 days ago (1 children)

then Division or Multiplication

There's neither, only Addition and Brackets (and Subtraction inside Brackets).

8-5= 3 3*5=15

Nope. 2+5(8-5)=2+(40-25), The Distributive Law, a(b+c)=(ab+ac)

Nope. 2+5(8-5)=2+(40-25), The Distributive Law, a(b+c)=(ab+ac)

Post picture declaiming brackets as a multiplication symbol, then proceeds to solve the problem to the exact same solution using distributive law to multiply both numbers within the bracket. Fucking genius.

Post picture declaiming brackets as a multiplication symbol,

What do you think the "B" step in BEDMAS is for?? 😂

proceeds to solve the problem to the exact same solution using distributive law to

Distribute the coefficient over the terms inside the brackets

Fucking genius

Says someone who can't tell the difference between Distributing, 2(1+3)=(2+6), and Multiplication, 2x(1+3)=2x4, 1/(2+6)=(1/8), 1/2x4=2
