put this solution on YOUR website!a < b
From this we understand that a is smaller than b.
In other words,b is greater than a.
Now,
suppose a is 3,and b is 5.
then b is still great than a
3 < 5
a < b
-3 ? -5
Now think,which is the BIGGER number ... -3 or -5?
the bigger number is -3.
Suppose you have 60 candles.let that be Z.
z-a > z-b
Is the above statement true or false?
It is true,because
60-3 > 60-5
Hence,
if a < b
then -a > -b
Hope this helps
You can
put this solution on YOUR website!Start with:
a < b (a less than b)
that's the same as saying
b > a
Look at
b > a
subtract a from both sides:
b-a > a-a
b-a > 0
subtract b from both sides:
b-a-b > -b
b and -b cancel out
-a > -b
