For example, the first expression 3 ט∘+ 4 expands to ט 3 + 4. Summing up, we get ט 7, which from the previous section is 7 × 7, or 49.

It's past time we covered how the syntax for modifiers works. Remember how I told you you hated learning the order of operations? No? Good. Modifiers bind more tightly than functions, so they are called on their operands before those operands can be used as arguments. As the parentheses above suggest, modifiers associate from left to right, the opposite order as functions. For example, the first expression above is evaluated in the order shown below. First we construct the square function ט, then compose it with +, and finally apply the result to some arguments.
