Set the variable "product" to be a multiple of the variables "a" and "b".

this is most likely the simplest answer, but i have reviewed the video lesson and cant seem to find the answer. I tried variations of
a = 2 b = 2 a * b = c etc etc.

you need to create a new variable named product, and on the right side of the = assign it the product of a and b

when working with variables and assigning them values, the variable name goes on left side of the equals sign, and the value you want to assign it goes on the right.

creating a variable generally looks like this:

variable_name = value

Ruby can do mathematical operations using operators such as *, / -, and +.

if we wanted to create a variable called sum and assign it a value of 2 + 3 it would be

sum = 2 + 3

if we had assigned 2 and 3 to variables it would be:

a = 2
b = 3
sum = a + b

so to assign a variable called product the product of a and b:

a = 6
b = 2
product = a * b
