Prove Closure property of addition of whole numbers, with p = 124 , q = 39 This proceeds as; p = 124 and it is whole number ----------(1) q = 39 and it is also a whole number------(2) Now, add the given whole numbers i.e. p and q; (p + q) = 124 + 39 = 163 163 is a whole number, or we can also say that (p + q) is also a whole number ------------(3) From (1), (2) & (3), we get If p and q are whole numbers, then (p + q) is also a whole number. Hence closure property of addition of whole number is proved. Related Question Examples Explain closure property for addition of whole number, with variables x and y. Prove Closure property of addition of whole numbers, with p = 124 , q = 39 Explain Closure property of addition of whole numbers, with numbers 25 and 1213 If a and b are whole numbers, then (a + b) will also be a whole number.
