Answer: -9
Step-by-step explanation: -5 - 4, the answer will be -9 because when you subtract a positive from a negative you get a negative, if you subtract a negative from a negative then the number will get more positive. Basically, if there are an odd number of minus symbols, then the number is going to decrease in value, however if there are an even number of minus symbols, then you are adding the number instead of subtracting as the minuses cancel out meaning that the number will go up in value. The only time where this rule is broken is like in this case where the number you are subtracting from is a negative, so even though there are an even amount of minus symbols, the number still decreases in value. If the number you are subtracting with is negative however, then you are still adding. One way to think of it is that IF THERE ARE AN ODD AMOUNT OF MINUS SYBOLS THEN THE ‘DIGITS’ NOT NUMBER, THE ‘DIGITS’ WILL GET SMALLER, AND IF THERE ARE AN EVEN AMOUNT OF MINUS SYMBOLS, THEN THE ‘DIGITS’ GET LARGER. So following this rule, in -4 - 5, there are an even amount of minus symbols even if the number is getting smaller, the digit is going from 4 to 9, meaning the digit is getting bigger.
Hope this helps.
