### Concatenate:

#set(\$string1 = "con") #set(\$string2 = "cat") #set(\$string3 = \$string1 + ' ' + \$string2)

First string: \$string1

Second string: \$string2

If I can mention both strings, like this: \$string1 \$string2, then why should I concatenate only to get this: \$string3 ????

### Increment

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

### Math

#set(\$score = "0")

A variable with "0" as its value: \$score

To Integer: \$_MathTool.toInteger(\$score)

#set(\$ice = 4)

If \${_EscapeTool.dollar}ice is 4, then \${_EscapeTool.dollar}ice cubed is \$_MathTool.pow(\$ice,3)

4 multiplied by 3 is \$_MathTool.mul(4,3)

4 divided by 3 is \$_MathTool.div(4,3)

4 minus 3 is \$_MathTool.sub(4,3)

Modulus: 4 mod 3 is \$_MathTool.mod(4,3)

A random number between 1 and 100: \$_MathTool.random(1,100)

Summation: Sum of 8, 6, 7, 5, 3, 0 and 9 = \$_MathTool.getTotal([8,6,7,5,3,0,9])

Maximum of 8, 6, 7, 5, 3, 0 and 9 = \$_MathTool.max(8,6,7,5,3,0,9)

Minimum of 8, 6, 7, 5, 3, 0 and 9 = \$_MathTool.min(8,6,7,5,3,0,9)

The average of 8, 6, 7, 5, 3, 0 and 9 = \$_MathTool.getAverage([8,6,7,5,3,0,9])

The average of 8, 6, 7, 5, 3, 0 and 9 rounded to the nearest whole integer = \$_MathTool.round(\$_MathTool.getAverage([8,6,7,5,3,0,9]))

The average of 8, 6, 7, 5, 3, 0 and 9 rounded to 2 decimal places = \$_MathTool.roundTo(2,\$_MathTool.getAverage([8,6,7,5,3,0,9]))
