Question 1 (Figure it out, Page number 6) For each number given below, write expressions for at least two different ways to obtain the number through button clicks. Think like Chitti and be creative. (a) 8300 Way 1: (8 × 1000) + (3 × 100) = 8000 + 300 = 8300. Way 2: (83 × 100) = 8300 Question 1 (Figure it out, Page number 6) For each number given below, write expressions for at least two different ways to obtain the number through button clicks. Think like Chitti and be creative. (b) 40629Way 1: (4 × 10,000) + (6 × 100) + (2 × 10) + (9 × 1) = 40,000 + 600 + 20 + 9 = 40,629 Way 2: (40 × 1,000) + (6 × 100) + (29 × 1) = 40,000 + 600 + 29 = 40,629 Question 1 (Figure it out, Page number 6) For each number given below, write expressions for at least two different ways to obtain the number through button clicks. Think like Chitti and be creative. (c) 56354 Way 1: (5 × 10,000) + (6 × 1,000) + (3 × 100) + (5 × 10) + (4 × 1) = 50,000 + 6,000 + 300 + 50 + 4 = 56,354 Way 2: (56 × 1,000) + (3 × 100) + (54 × 1) = 56,000 + 300 + 54 = 56,354 Question 1 (Figure it out, Page number 6) For each number given below, write expressions for at least two different ways to obtain the number through button clicks. Think like Chitti and be creative. (d) 66666 Way 1: (6 × 10,000) + (6 × 1,000) + (6 × 100) + (6 × 10) + (6 × 1) = 60,000 + 6,000 + 600 + 60 + 6 = 66,666 Way 2: (66 × 1,000) + (666 × 1) = 66,000 + 666 = 66,666 Question 1 (Figure it out, Page 6) For each number given below, write expressions for at least two different ways to obtain the number through button clicks. Think like Chitti and be creative. (e) 367813Way 1: (3 × 1,00,000) + (6 × 10,000) + (7 × 1,000) + (8 × 100) + (1 × 10) + (3 × 1) = 3,00,000 + 60,000 + 7,000 + 800 + 10 + 3 = 3,67,813 Way 2: (36 × 10,000) + (78 × 100) + (13 × 1) = 3,60,000 + 7,800 + 13 = 3,67,813
