For -4+2 you’d start at -4 then add two headed to the positive side
The sum of the expression -4 + 2 - 4 - 2 is shown on the number line that is negative 8.
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression is given below.
⇒ -4 + 2 - 4 - 2
Firstly, subtract 4 from zero, then the line goes from zero to negative 4.
Secondly, add 2 from -4, then the line goes from negative 4 to -2.
Thirdly, subtract 4 from -2, then the line goes from negative 2 to -6.
And finally, subtract 2 from -6, then the line goes from negative 6 to -8.
Thus, the sum of the expression -4 + 2 - 4 - 2 is shown on the number line that is negative 8.
