Question

use the number line to work out -4×3​

Answer 1

Topic - Number Line

Steps to find the product ( - 4 × 3 ):

1. Draw a number line with some positive and negative points, and point out 0, 1, 2, ... and - 1, - 2, - 3, ... points on the number line.
2. Since there is negative number ( - 4 ), we go 4 units once, towards the left. So it is ( - 4 × 1 ).
3. Now, go another 4 units towards the left starting from ( - 4 ). So it is ( - 4 × 2 ).
4. Again go another 4 units towards the left starting from ( - 8 ). So it is ( - 4 × 3 ).
5. Now check the points. It is ( - 12 ).

Answer: Therefore we conclude that ( - 4 × 3 ) = - 12, using number line.
