Answer 2

Explanation of Expressions

In the game, the boy used 28 parts to build a car and 16 parts fewer to build a trailer. Let's explain what the expressions "28 minus 16" and "28 plus (28 minus 16)" mean, and what "130 minus 28" represents.

28 minus 16: This expression represents the result of subtracting 16 from 28. In this context, it indicates the difference in the number of parts used for the car and the trailer.

28 plus (28 minus 16): This expression involves two operations. First, it calculates the result of the expression "28 minus 16," and then adds the result to 28. This could represent the total number of parts used for both the car and the trailer.

130 minus 28: This expression represents the result of subtracting 28 from 130. It could indicate the total number of parts available for use in the game.

Let's proceed to calculate these expressions.

Calculation

28 minus 16: 28 - 16 = 12

28 plus (28 minus 16): 28 - 16 = 12 28 + 12 = 40

130 minus 28: 130 - 28 = 102

Conclusion

In conclusion, the expressions represent the following: - 28 minus 16 equals 12, which is the difference in the number of parts used for the car and the trailer. - 28 plus (28 minus 16) equals 40, which could represent the total number of parts used for both the car and the trailer. - 130 minus 28 equals 102, which could represent the total number of parts available for use in the game.

These calculations help understand the significance of the given expressions in the context of the game.
