Can you tell me what -15 + 4 equals and the process of how you got that answer

-15 is 15 below o

 you are adding 4 , so you are getting closer to 0

 so you would actually use subtraction, 15-4 = 11

 since 15 is negative, and you are adding a number smaller than 15, the answer would be negative so it would be -11

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
