In these expressions, the plus and minus signs in front of the numbers indicate whether the number is positive or negative. In arithmetic, subtraction of two numbers is the same as adding the first number and the opposite of the second number.
In the first example, 5 - 9 = -4, which means 5 minus 9 is equal to -4.
In the second example, -3 - 8 = -11, which means -3 minus 8 is equal to -11.
In the third example, -7 - 0 = -7, which means -7 minus 0 is equal to -7.
In the fourth example, 3 - 3 = 0, which means 3 minus 3 is equal to 0.
In the fifth example, 1 - (-9) = 10, which means 1 minus -9 is equal to 10.
