Given:
Number of positive tiles = 4
Number of negative tiles = 7
To find:
The correct sum of tiles=?
Solution:
- The model here depicts four tiles labeled as "positive" and seven tiles labeled as "negative".
- This implies calculating the sum of the given two integers.
- Therefore find the sum of given integers in the following way:
=> = + 4 tiles + (-7 tiles)
=> = + 4 tiles -7 tiles (∵ plus into minus implies minus for the integers)
=> = -3 (The answer always gets the sign of the highest number)
Hence, negative 3 or -3 (option A) is the correct sum of the model.
