Question

List all the elements of the following set you sent no tax

Answer 1

Notice that the integers 1, 2, 3, 4, 5 and 6 are not greater than 6. All the integers from the number 7 on are greater than 6.

Therefore, the set of all whole natural numbers that are not greater than 6 is:

`\mleft\lbrace1,2,3,4,5,6\mright\rbrace`
