What echo has do with Return value?

#In this script I call function what has echos in it and another witch does
not have echos. Both should return value $false = False [int]0 or something
like that?!

function tester
{
echo "I return this and:"
return $false
}

function testerNoEcho
{
return $false
}

$testing2 = (tester)

'Tests:'

'1'
echo $testing2
'2'
echo ("($testing2)")
'3'
echo "($testing2)"
'4'
echo ($testing2)
'5'
echo "$testing2"
'6'


If ($testing2 -eq $false)
{
echo "YAY it worked!"
}
else
{
echo "oups, what happened?"
}


$testing2 = (testerNoEcho)

'Tests:'

'1'
echo $testing2
'2'
echo ("($testing2)")
'3'
echo "($testing2)"
'4'
echo ($testing2)
'5'
echo "$testing2"
'6'



If ($testing2 -eq $false)
{
echo "YAY it worked!"
}
else
{
echo "oups, what happened?"
}


#This script outputs:

Tests:
1
I return this and:
False
2
(I return this and: False)
3
(I return this and: False)
4
I return this and:
False
5
I return this and: False
6
oups, what happened?
Tests:
1
False
2
(False)
3
(False)
4
False
5
False
6
YAY it worked!


#Why does it return THE return value AND echos from function
#It is supposed to return THE return value right?
#Or how I can get function return value without getting all echos messing it
up

echo is an alias for write-output.

Write-Output writes objects to the success pipeline. Try using write-host instead.

PS ps:\> get-help write-output
PS ps:\> get-help write-host
