Final answer:
To convert the addition equation -36+(-20)=t to a subtraction equation, it becomes -36 - 20 = t, as subtracting a negative number is the same as adding its positive equivalent.
Step-by-step explanation:
To write the addition equation -36+(-20)=t as a subtraction equation, we'll use the principle that subtracting a negative is the same as adding a positive. First, remember that when we subtract a negative number, it's similar to adding its opposite. In this case:
-36 + (-20) is the original equation for addition. To write this as subtraction, we change +(-20) to subtract the positive counterpart of 20, so we get:
-36 - 20 = t.
This transformation uses the rule that in subtraction, you change the sign of the subtracted number and then follow addition rules. It's similar to the provided example, where subtracting -6 from 2 is the same as adding 6 to 2 (2-(-6)=2+6). So, no matter if you're dealing with positive or negative numbers, subtracting a negative is equivalent to adding the absolute value of that number.
