With whole numbers, there are five ways.
In whole numbers, 2. 1 * 13 = 13
There are infinitely many answers. Let A be any whole number and let B = -A -20 Then by the closure of integers, B must be a whole number. And A + B = A + (-A - 20) = -20 Since A is arbitrary, there are infinitely many ways of choosing A and so there are infinitely many ways in which two whole numbers will make -20.
Write 2 ways in which whole numbers and decimal numbers are different
5 different ways isn't it
Whole numbers are a proper subset of decimal numbers. All whole numbers are decimal numbers but not all decimal numbers are whole numbers.
There are 8 different pairs of whole numbers whose prodcut is 40. Allowing for commutativity (a*b = b*a), there are 16 possible ways.
If you restrict yourself to positive whole numbers, there are four.
10x5 and 1x50
It would be 5 ways
2. 4 if you include negatives.
With a pen, with a pencil, and with a crayon.
