DO YOU STILL REMEMBER?
10 = 10 x 1
100 = 10 x 10
1 000 = 10 x 10 x 10
10 000 = 10 x 10 x 10 x 10
100 000 = 10 x 10 x 10 x 10 x 10
1 000 000 = 10 x 10 x 10 x 10 x 10 x 10
DO YOU ALSO REMEMBER?
We can write the number in a shorter way by using the POWERS OF TEN.
10 = 101 (10 to the power of 1)
100 = 102 (10 to the power of 2)
1 000 = 103
10 000 = 104
100 000 = 105
1 000 000 = 106
Learning Outcome 1: The learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems.
Assessment Standard 1.9: We know this when the learner performs mental calculations involving:
1.9.2: multiplication of whole numbers to at least 12 x 12.
