What is the best strategy to use if we want to find out how many different scores are possible with 3 arrows?

Make a table and use patterning.

Patterns, connections, and functions constitute a binding topic of arithmetic. From the soonest age, understudies ought to be urged to research the patterns that they find in numbers, shapes, and articulations, and, thus, to make scientific disclosures. They ought to have chances to break down, expand, and make an assortment of patterns and to use pattern-based reasoning to comprehend and speak to numerical and other true marvels. These investigations show boundless open doors for critical thinking, making and confirming speculations, and building numerical comprehension and certainty.

Arithmetic is regularly viewed as the study of patterns. When taking care of a mind boggling issue, we often recommend to understudies that they attempt to deal with easier renditions of the issue, watch what occurs in a couple of particular cases — that is, search for a pattern — and use that pattern to take care of the first issue. This pattern-based reasoning, utilizing patterns to dissect and take care of issues, is an amazingly capable apparatus for doing mathematics.
