• At , why does Sal add a new line? Can't he just keep writing the numbers on the same line?
• He made a number grid,not a number line.
• Did most ancient civilizations develop a base 10 number system like us?
• When ancient people began to count, they used their fingers, pebbles, marks on sticks, knots on a rope and other ways to go from one number to the next. As quantities increased, more practical representation systems became necessary.
• Why are numbers 1 through nine? Is there a system of counting based on something other than ten?
• The system of counting today that is most commonly used is the decimal system, with the digits 0 through 9. Because there are 10 different digits, it is said to be a base 10 system. However, there are many other systems with different bases.

For example, the binary system is base 2 and is commonly used in computers. Also, the ancient Sumerians and Babylonians used a base 60 system, which is why we have 60 seconds in a minute and 60 minutes in an hour.

Also, this online calculator converts numbers between systems with different bases: https://baseconvert.com/

• can't you only go to 100 on a number grid or is it wrong or right to add 101-120?
• No! It is definitely not wrong to add numbers to the number grid. Number grids are basically infinite, but the normally only go to 100.
• How do you count to 1,000
• well you can count to 100 10 times and that would be 1000
• what's this number called 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
• It is called one quattuordecillion, but the thing is, it isn't even the biggest named number. The biggest number that has a name is a Googolplex. It's 1 followed by a googol of zeros :

• Do number grids go onto big numbers?
• This a number grid so, should we must start on 0? Why can't we start on -10 or somewhere else?
• You actually can start from -10, but when we are dealing with positive numbers, we usually start with zero because there is no use of writing negative numbers.
