Math Factors are numbers that divide evenly into another number. For instance 10-the factors would be 1,2,5 and 10 . All numbers divide evenly into 10.
Choose any number for the first number. Subtract 10 minus the number you chose to get the second number.

It is a number with two digits in it. So it goes into the "tens" place of the numbers. Basically any whole number from 10 to 99. See how any number between those numbers only has 2 numbers, or digits that make up the number? 9 would only be a single-digit number, and 100 would be a triple-digit number.
I am not sure if any two consecutive numbers can add up to an even number.
Lets just say you have an answer of 7.89, OK? By rounding that number up, you make it 8. When you round up numbers, you take your number and kinda 'pull' it up to the closest whole number.
Add the numbers then divide the sum by the number of numbers you added e.g. average of 1,2,3,4 four numbers add em up 1+2+3+4 =10 divide the sum by the number of numbers 10/4 average of 1,2,3,4 is 2.5
28 and 10 are both triangular numbers and add up to 38
