Hello everyone, How would it be to develop an activity for both sugar and sugarizer which can help the students to learn different mathematical tricks to improve their calculation speed?
For example: Let us find (x5)² Step 1: Think of the number next to x. Step 2: x * number next to x Step 3: Put 25 at the end of the answer. Answer = Step 2 (concat) 25 Find (45)² =? Step 1: 45 * 45 = .......25 Step 2: 4*(4+1) = 4*5 = 20 [here number next to 4 is 5(not adjacent but after 4)] Hence the answer will be 2025 I would appreciate your feedback. Thank you
