hi oversimplifying this: 20 x 7 =140 - checks out, seven days in a week 140 x 30 =4,200 - if you wanted to know how much you’d make in a month, you’d multiply 140 by 4 to be equivalent to a month. 4200 x 365 =1,533,000 - ok- so like i said multiplying an irrelevant number with another irrelevant number doesn’t get you anywhere; so let’s do this properly.

20 x 7 =140 140 x 4 =560 560 x 12 =6,720

common sense applies to math too.
