What is -3 minus 7?

Explanation:
Subtracting a positive number from a negative number makes the result more negative. Treat subtraction as adding the opposite: -3 - 7 is the same as -3 + (-7). Add their magnitudes: 3 + 7 = 10, and keep the negative sign, giving -10. If you picture a number line, start at -3 and move 7 steps to the left, landing at -10. This is why the result is -10.
