Common questions
To simplify negative number operations, change the sign of the second number being added or subtracted before performing the operation.
When adding or subtracting integers, the operation depends on the signs and absolute values of the numbers involved.
To evaluate multiple operations in a row, perform the operations from left to right.
- When adding two integers with different signs, subtract the absolute values and take the sign of the number with the larger absolute value.
- Students in grades K-6
- Believing that changing the sign of a number changes its absolute value
- When adding two integers with the same sign (both positive or both negative), combine their absolute values and keep the same sign.
- Failing to consider the signs and absolute values of numbers
- Being overwhelmed by complex problems
- Presuming that integer operations are only relevant for low-level math problems + -2 + (-4) = -6
- Adult learners looking to refresh their math skills
- Educators teaching integer arithmetic to students + 5 + 3 = 8
- When subtracting an integer, change the sign and add the numbers.
- Using incorrect rules or procedures
- High school students reviewing basic operations
