You can either just add them up or use quick logic to add them in pairs: All the numbers from 1 to 49 match up with 51 through 99 to = 49 pairs of 100 = 4900, than add the two you skipped 4900 + 50 + 100 = 5050 total
You add the numbers they give you and divide by the amount of numbers they give you. For example: Find the median of these numbers 20,30,40,50 Since there is 4 numbers add them up, and you get 140 So then do 140÷4=35
Product = multiply.

Factors multiply. The same set of numbers won't add up to both 140 and 240, but 120 and 20 are factors of 240 that total 140.

140 just multiply 7x2 then add a zero
