Answer Key - Chapter 3 A Story of Numbers

1-b, 2-b, 3-b, 4-a, 5-b, 6-b, 7-c, 8-b, 9-c, 10-c, 11-b, 12-b, 13-d, 14-b, 15-b, 16-a, 17-a, 18-a, 19-a, 20-c

Detailed Solutions with Tricks

Q1 & Q2. Trick: Earliest counting = one-to-one mapping. Gumulgal people had only words for 1, 2. For 3 they said "two-one", for 4 "two-two". So grouping idea starts early.

Q3. Numerals: Numbers are ideas, numerals are symbols to write them. Like 5 is a number, '5' is a numeral.

Q5 & Q15. Roman Trick: If smaller before larger, subtract. IV = 5-1=4, XL = 50-10=40. If smaller after, add. VI = 5+1=6.

Q6, Q13 & Q17. Main Difference: Roman has NO place value and NO zero. You have to add values of all symbols (XXX = 10+10+10). Hindu has place value + zero, so very short and efficient.

Q7 & Q8. Must Remember Base: Mesopotamian = Base 60 (60 seconds, 60 minutes came from there!), Mayan = Base 20 (dots and bars, counted with fingers + toes), Egyptian & Hindu = Base 10

Q9 & Q11. Most Important: Zero and place value invented in India 2000 years ago. Our system = Base 10, 10 numerals 0-9.

Q12. Tally Trick: Tally marks grouped in 5s (four vertical lines + one cross line) for fast counting.

Q14. Egyptian Trick: They had different pictures for 1, 10, 100, 1000. These are called Landmark numbers - powers of base.

Q18. Base Rule: Base-n needs n numerals. Base-5 needs 0,1,2,3,4 = 5 numerals. Base-10 needs 10 numerals (0-9).
