8 - 24 = -16
Think of the Number Line
-18,-17,-16,-15,-14-13-,12,-11,-1,-9,-8,-7,-6,-5,-4,-3,-2,-1,01,2,3,4,5,6,7,8,9,10
We start at '8'. The guide says move to the left for subtraction/take away/minus. So we move '24' places to the left, we will end up on '-16'.
Hence 8 -24 = -16
NB the number line can be extended to positive infinity to the right and negative infinity to the left.
Hope that helps!!!!
