Add and subtract by counting forward or backward on the number line.
$2 + 5 - 4$

Open in App

Solution

$2 + 5 - 4 = (2 + 5) - 4$
$= 7 - 4$
$= 3$
We know that, if we move toward left/backward on the number line, we will get the subtraction of the numbers.
Here, if we move $4$ steps left from $7$ , we will reach at $3$
Hence, the required answer is $3$
