Concatenate, Increment and $_MathTool

Concatenate:

First string: con

Second string: cat

If I can mention both strings, like this: con cat, then why should I concatenate only to get this: con cat ????

Increment

I can simply set a numeric variable equal to itself + 1 OR I could use one of the items below:

Math

A variable with "0" as its value: 0

To Integer: 0

Add 1: 1

4 cubed is 64

4 multiplied by 3 is 12

4 divided by 3 is 1.3333333333333333

4 minus 3 is 1

Modulus: 4 mod 3 is 1

A random number between 1 and 100: 60

Summation: Sum of 8, 6, 7, 5, 3, 0 and 9 = 38

Maximum of 8, 6, 7, 5, 3, 0 and 9 = 9

Minimum of 8, 6, 7, 5, 3, 0 and 9 = 0

The average of 8, 6, 7, 5, 3, 0 and 9 = 5.428571428571429

The average of 8, 6, 7, 5, 3, 0 and 9 rounded to the nearest whole integer = 5

The average of 8, 6, 7, 5, 3, 0 and 9 rounded to 2 decimal places = 5.43
