The numbers 4 and -4 are called what?

Explain to a student how to use signed counters to evaluate this problem: -4 – 2

IS 454,000,824,016 DIVISIBLE BY 4?

Name the problem BEST represented by the signed counters.

IS 310,102,120,231 DIVISIBLE BY 3?

Name the number of rectangle arrays can be created for the number 20. Assume commutative arrays (like 1×3 and 3×1) count as the same array.

IS 300,600,00,135 DIVISIBLE BY 9?

Name the number of rectangle arrays that can be created for the number 24. Assume commutative arrays (like 1×3 and 3×1) count as the same array.

Use the multiples list to find the LCM for 12 and 9.

Name the problem represented by the signed counters.
