Tips
A common mistake is to perform the operations in the wrong order, or to misinterpret the signs of the numbers. For example, someone might calculate $5-6$ first and then add $-2$ to that result, which is incorrect. Adhering to the correct order of operations (from left to right in this case) and paying careful attention to signs can prevent these errors.
