+### Expression Evaluation
+
+To evaluate an expression, we use the keyword `EXPR`.

+Consider the following code snippet:

+```
+MOV $var1 2
+MOV $var2 3

+EXPR ( $var1 + 5 ) * -10 / $var2
+RPXE $out
+
+PRT $out $ENDL
+```
+
+Here, the compiler evaluates the expression `( $var1 + 5 ) * -10 / $var2` and `RPXE` stores the result in the variable `$out`.
+And prints the value of `$out` followed by a newline character.
