20 True or False: If you count 10 objects, then take 3 away, and count again carefully one by one, the count will be 7. Explain your answer.
Q17. 50 − 18 = 32; 32 − 7 = 25 mangoes left on tree. Q18. Total = 30; 30 − 15 = 15 candies left. Q19. Missing = 998; Number just after 1000 = 1001. Q20.True. Counting is accurate regardless of order. If you start with 10 and remove 3, careful counting one by one will always give 7.
