Rounding a number means replacing it by another value that is a simpler, shorter approximation, while keeping its value close to the initial one. The rounded number will be less accurate, but easier to work with. Positive and negative numbers are rounded off to whole or decimal places: half up, half down, half away from zero, half towards zero, half to even, half to odd, to ceiling, to floor.

Calculate the sum and learn how to add multiple digit numbers using the column adding method, from right to left (carrying over if the case): 1. Stack the numbers on top of each other. 2. Add their digits column by column starting from the columns on the right. If the result of a two digit addition is more than 9, carry over the excess bit of 1 to the next left column.

Calculate the difference and learn how to subtract multiple digit numbers using the column subtracting method, from right to left (borrowing from the higher place value column if the case): 1. Stack the numbers on top of each other. 2. Subtract column by column starting from the column on the right. If the second digit is larger than the first borrow 10 from the next column to the left.
