Bianca uses point p to represent the sum of 2.6 + (-1.4). 2.6 + (-1.4)=p
we know that
2.6+(-1.4)=2.6-1.4=1.2
therefore
In a number line the point P must be equal to +1.2
so
1.2 units at right of the zero number
Part 2
i will assume that
the question is find out the distance between -1.4 and 2.6
so
the distance is
2.6-(-1.4)=2.6+1.4=4.00
therefore
the reasoning Of Bianca is incorrect
and point P is 4.00
