#6#

Explanation:

#color(red)(-8)# is 8 units to the left of 0 on the number line

From #color(red)(-8) " count on 14 units to the right "#

You should arrive at +6

That is #-8+14=6#

Another approach

#-8+14=6#

Explanation:

Splitting (partitioning) #color(red)(14)# into #" "color(red)(8+6)#

Write #color(green)(-8color(red)(+14))# as #" "color(green)(-8color(red)(+8+6))#

But #-8+8=0# giving

#0+6#

So #-8+14=6#
