الدليل
This studio follows the strategies of chapter 1 of the Iranian Grade 7 book: making a pattern, sub-problems and a simpler problem. The steps are the same: understand the problem, choose a strategy, solve it and check your answer.
Making a pattern: so that no case is missed, write the cases in order in a table and find the pattern, for example by making the first number one bigger each time.
تجزئة المسألة: split the big problem into smaller ones and use the answer of each part in the next.
حل مسألة أبسط: round big numbers to see which operation is needed, then solve with the real numbers.
