1. Mathematical functions
1. ABS(number): Returns the absolute value of a number
Syntax: ABS (number); return the absolute value of the number; if you refer to a cell, just replace the number with the cell address
2. INT(number): Round to the smallest
Syntax: INT (number); if you refer to a cell, just replace the number with the cell address
3. MOD(number,divisor): Returns the remainder of the division of two numbers (the sign of the result is the same as the remainder)
Syntax: MOD (divisor, divisor); if you refer to a cell, just replace the number with the cell address
4. RAND: random number between [0,1)
5. RANDBETWEEN(bottom,top): random number between [a,b]
6. ROUND(number,num_digits): Round the number to the specified number of digits
7. SQRT(number): returns the arithmetic square root
Case: find the arithmetic square root of 16
