Final answer:
The negative number that adds to 7 to get 1 is -6. This problem involves basic arithmetic operations with negative and positive numbers, specifically addition and subtraction to solve for the unknown.
Step-by-step explanation:
The student asked, "What negative number adds to 7 to get 1?" This is a mathematics problem that involves understanding the rules of addition with negative numbers. To solve this, we are looking for a number 'x', such that when added to 7, gives us 1. Mathematically, we can express this as:
7 + x = 1
To find 'x', we need to isolate it on one side of the equation. We do this by subtracting 7 from both sides of the equation:
7 + x - 7 = 1 - 7
x = -6
So, the negative number that adds to 7 to get 1 is -6. This is in line with the rules of addition involving negative numbers. When a positive number like 7 is added to a negative number such as -6, you subtract the absolute value of the negative number from the positive number which results in 1.
