Standard Mathematical Procedure for Adding Mixed-Sign Financial Adjustments

Project Budget Reconciliation

Adding $-1 + (-4)$, $-1 + 5$, and $1 + (-5)$ with Counters

Adding $-2 + (-4)$, $-2 + 4$, and $2 + (-4)$ with Counters

Adding $-5 + 3$ and $5 + (-3)$ with Counters

Translating and Simplifying 'the sum of $8$ and $-12$, increased by $3$'

Arrange the steps in order to find the sum $-5 + 3$.

In the two-color counter model, what is the pairing of one positive counter and one negative counter called?

When adding a positive and a negative integer, match each addend condition to the sign of the sum.

To find $-5 + 3$, which operation do you use on the absolute values $5$ and $3$?

When adding integers with opposite signs, subtract the smaller absolute value from the larger absolute value.

How do you add two integers with different signs?
