Question

Hey i was hoping you could tell me what these mean cause I've never seen them before

Answer 1

First of all, you should remember that:

`2=(2)/(1)`

All number is equal to that number divide by 1. Like the example of 2.

After that we apply the next law (i draw it):

First you represent the numerator of fraction (2) in a fraction number 2/1... because is the same like I told you before.

After that, You multiply the numbers at the extreme (light blue) 2 * 11 and put that result at the new numerator.

Later, the numbers in the inside will be multiplied (dark blue) 1*3 and put that resoult in the denominator.

Finally, you simplify if you can. This isn't the case. And that's it.
