Question

Find the answer using number line:
Silvia brought 17 toffees from a candy store. In 5 days she ate a total of 8 toffees. The number of toffees left with her .

Answer 1

Silvia had 17 toffees.
She ate total 8 toffees.

Number of toffees left with her $=17-8$

Let's subtract 8 from 17 using number line with the help of Burgy

Burgy starts at 17, he jumps 8 hops of 1 unit each and reaches 9
Thus, 17 - 8 = 9
Finally, she has 9 toffees.
