	The four arithmetical operations supported by BR are addition, subtraction, multiplication and division. These operations literally correspond with their respective mathematical operators. Each of these operators may be followed by an equal sign, in which case the result of the operation is assigned to the variable on the left side of the operator:		#redirect:[[:Category:Arithmetic Operations]]

The four arithmetical operations supported by BR are addition, subtraction, multiplication and division. These operations literally correspond with their respective mathematical operators. All of these mathematical operators are examples of [[Binary operators|binary operators]].

Now consider two more operators that use the same signs as addition and subtraction, yet each perform a different function.

The first one is [[Unary operators|unary plus]] '''+'''. The result of the unary plus operator is the value of its operand. The operand to the unary plus operator must be a numeric variable.

For example,

00010 let b = - 1
00020 let a = + b

The second one is [[Unary operators|unary minus]] '''-'''. The result of the unary minus operator is the opposite value of its operand. The operand to the unary minus operator must be a numeric variable.

For example,

00010 let b = - 1
00020 let a = - b

As a result, the value of a becomes 1, which is the opposite of -1.
