Write a number sentence to represent the model. Explain how you determined the number sentence.
(+) (+) (+) (+) (-) (-) (-) (-) (-) (-) (-)
Sure, here's a number sentence to represent the model:
4 + 7 + 2 + 9 - 6 - 1 - 8 - 5 - 3 - 10
I determined this number sentence by assigning positive values to the numbers with the plus sign and negative values to the numbers with the minus sign, following the order from left to right. The plus signs indicate addition and the minus signs indicate subtraction.
To represent the given model, we can use the following number sentence:
(+4) + (+3) + (+2) + (+1) - (-1) - (-2) - (-3) - (-4) - (-5) - (-6) - (-7)
In this number sentence, the plus (+) signs represent positive numbers and the minus (-) signs represent negative numbers. By assigning positive numbers to the plus signs and negative numbers to the minus signs, we can represent the model accurately.
To represent the given model with a number sentence, we need to assign each operation with the respective number of positives (+) and negatives (-) symbols.
Let's break down the model:
(+) (+) (+) (+) (-) (-) (-) (-) (-) (-) (-)
This model has 4 positive symbols (+) followed by 6 negative symbols (-).
Therefore, the number sentence representation of the model is:
4 + 6 = 0
The number sentence represents that adding 4 positives and 6 negatives will result in 0.
