Create a story for 3 + 20 ÷ 5 - 1. The story should clearly reveal why 20 ÷ 5 is "glued together" (ie. a multiplicative bundle).
Question 2 For the arithmetic expression, 1 + 2 x 3 + 4 + 5 x 6 + 7 x (2 + 3 x 4):
a) underline all multiplicative bundles
b) determine its value
Question 3
For the arithmetic expression, 2 + 3 x 10 ÷ 6 - 4 x 1 + 28 ÷ 4 + 2 x [3 + 4 x (10 - 2 x 3)],
determine its value in TWO significantly different ways (not simply a minor change).
