negative numbers and positive numbers

Question

is -1.6 higher or lower than -2.3

Answer 1

plot two points on the y axis (0, -1.8) and (0, -2.3)

they're both on the vertical axis, the y axis

and the y coordinate -1.8 is higher than the y coordinate -2.3

-1.8 > -2.3

or look at the real number line, a one dimensional view

the larger numbers are to the right

-1.8 is to the right of -2.3
