Problema Solution
can the sum of two numbers be smaller than either of the numbers? illustrate
Answer provided by our tutors
let 'x' and 'y' be the numbers
if x + y < y
x < y - y
x < 0
if x + y < x
y < 0
we conclude that this is possible when at least one of the numbers is negative.
for example x = -3 , y = 5
-3 + 5 = 2 < 5
for example x = -3 , y = -5
-3 - 5 = -8 < - 5
