How is the product of 2 and -5 shown using integer tiles ?

Each tile is either marked with a plus sign or a minus sign to indicate "positive 1" or "negative 1" respectively.

Combining the tiles is basically adding 1 or negative 1 together.

Look at choice C and notice we have 2 sets of a group of 5 "negative 1" tiles, giving 2*5 = 5+5 = 10 of such tiles total. The final result is -10. You can think of it like "10 IOUs" or "you are 10 dollars in debt".

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
