Question

How do you use a number line to solve 235+123

Answer 1

235+123 on q number line:
200+100+30+20+5+3

Answer 2

we know that

Number line refers to a mathematical process of solving the equation with the use of lines.

we have

`235 + 123`

Starting from
`0` you count
`1` up to
`235`. Then starting from
`235` you additionally count another
`123`.

Then from zero start counting the total number to the line you stopped when adding
`123` to
`235`.

This simply equals to

`235+123=235+(100+20+3)\\ =335+20+3\\ =355+3\\ =358`
