Triangluar numbers or triangle numbers are numbers formed from the summation of all the numbers smaller than them. The first few triangle numbers are 1,3,6,10,15,21... If you think of a pyramid with a base of two blocks, and one on top, there are three blocks. If you add a base of three to that pyramid, you have six blocks. Then ten, and fifteen and so on. That is why they are called Triangle numbers.
What is base in numbers
Find the length of the two sides of base. Add the two numbers. Then multiply by 2.

base 4 would use the digits 0,1,2,3 so the first place digit would be 1,2,3 the 2nd place would be 0,1,2,3 and the 3rd place would be 0,1,2,3 3x4x4 =48

A three digit number cannot be divisible by a 5 digit number - in any base.
No. Egyptians did not invent numbers. Numbers used for counting were first used tens of thousands of years ago, before written history and thus before there are known civilizations. As for base or place number systems, the Myans are believed to be the first to create such a number system. It was base 60. Then the Egyptians invented a 10 base number system.
Assuming you're asking about IEEE-754 floating-point numbers, then the three parts are base, digits, and exponent.
