MaSH can perform standard arithmetic operations.

## Natural

mash

```
# Declare two numeric variables
set a to 4
printline "a is set to {{ a }}"
set b to 9
printline "b is set to {{ b }}"
# Add b to a
printline "a plus b is {{ a + b }}"
# Subtract b from a
printline "b subtract a is {{ b - a }}"
# Multiply a by b
printline "a multplied by b is {{ a * b }}"
# Divide b by a
printline "b divided by a is {{ b / a }}"
# Remainder of a divided by b
printline "remainder of a divided by b is {{ a % b }}"
# Raise b to power of a
printline "b to the power of a is {{ b ** a }}"
```

## Standard

mash

```
# Declare two numeric variables
a = 4
printline("a is set to {{ a }}")
b = 9
printline("b is set to {{ b }}")
# Add b to a
printline("a plus b is {{ a + b }}")
# Subtract b from a
printline("b subtract a is {{ b - a }}")
# Multiply a by b
printline("a multplied by b is {{ a * b }}")
# Divide b by a
printline("b divided by a is {{ b / a }}")
# Remainder of a divided by b
printline("remainder of a divided by b is {{ a % b }}")
# Raise b to power of a
printline("b to the power of a is {{ b ** a }}")
```

## Output

output

```
a is set to 4
b is set to 9
a plus b is 13
b subtract a is 5
a multplied by b is 36
b divided by a is 2.25
remainder of a divided by b is 4
b to the power of a is 6561
```

Operators can also be chained together. They follow normal order of operations and you should use parentheses to indicate an alternative order:-

## Natural

mash

```
# Declare two numeric variables
set a to 5
set b to 10
# This will print 7.5
printline b - a / 2
# This will print 2.5
printline (b - a) / 2
```

## Standard

mash

```
# Declare two numeric variables
a = 5
b = 10
# This will print 7.5
printline(b - a / 2)
# This will print 2.5
printline((b - a) / 2)
```

## Output

output

```
7.5
2.5
```
