What is pemdas i am just learning it

PEMDAS stands for:

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Here is an easy equation to start off:

17 x 3 + 15 ÷ 3

= we first multiply 17 and 3 then the answer would be 51

51 + 15 ÷ 3

= then we divide 15 and 3 and the answer is 5

51 + 5

= last thing we add 51 and 5 then we get the answer of 56

so the final answer is 56!

17 x 3 + 15 ÷ 3

= 51 + 15 ÷ 3

= 51 + 5

=56!

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides

step-by-step explanation:

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
