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

8-5= 3

3*5=15

15+2=17

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)

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
