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!

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
