60: First digit can be any of 5, second any of 4 and last any of the remaining 3, so 5 x 4 x 3
It depend how many negative numbers are written on the cube.
This is called an orderd pair. It is written as (x,y).
There is more than one notation, but the open interval between a and b is often written (a,b) and the closed interval is written [a,b] where a and b are real numbers. Intervals may be half open or half closed as well such as [a,b) or (a,b]. For all real numbers, it is (-infinity,+infinity), bit use the infinity symbol instead (an 8 on its side).
Most people prefer to write numbers using digits since this is far shorter than writing out the relevant words.
If there are 15 different toppings, and each one can be either on the pizza ornot on the pizza, then the quantity of possibilities is the same as the quantityof binary numbers that can be written with 15 bits.Also the same as the greatest quantity of columns that a spreadsheet can havein Excel 97, the total memory that a program in QwikBasic can address, and thetotal physical memory that each computer aboard Apollo 11 had.That's 65,535, usually called "64 K".Save me a slice of any meatless one.

They can. And if you include repeating 0s and repeating 9s, then all rational numbers can be written with infinitely long repeating digits.
