Solution 1: Subtraction

To find the number of chocolate bars left in the box, we can subtract the number of chocolate bars taken for the younger group and the number taken for the older group from the total number of chocolate bars in the box.

Total number of chocolate bars in the box: 45 Number of chocolate bars taken for the younger group: 18 Number of chocolate bars taken for the older group: 16

To find the number of chocolate bars left in the box, we subtract the number of chocolate bars taken for both groups from the total number of chocolate bars: 45 - 18 - 16 = 11

Answer: There are 11 chocolate bars left in the box.

Solution 2: Addition and Subtraction

Another way to solve the problem is by using addition and subtraction. We can add the number of chocolate bars taken for both groups and then subtract it from the total number of chocolate bars in the box.

Total number of chocolate bars in the box: 45 Number of chocolate bars taken for the younger group: 18 Number of chocolate bars taken for the older group: 16

To find the number of chocolate bars left in the box, we add the number of chocolate bars taken for both groups and then subtract it from the total number of chocolate bars: (18 + 16) - 45 = 34 - 45 = -11

Answer: There are -11 chocolate bars left in the box.

Solution 3: Multiplication and Subtraction

We can also solve the problem by using multiplication and subtraction. We can multiply the number of chocolate bars taken for the younger group by the number of chocolate bars taken for the older group and then subtract it from the total number of chocolate bars in the box.

Total number of chocolate bars in the box: 45 Number of chocolate bars taken for the younger group: 18 Number of chocolate bars taken for the older group: 16

To find the number of chocolate bars left in the box, we multiply the number of chocolate bars taken for both groups and then subtract it from the total number of chocolate bars: (18 * 16) - 45 = 288 - 45 = 243

Answer: There are 243 chocolate bars left in the box.

In conclusion, there are different ways to solve the problem. Using subtraction, we find that there are 11 chocolate bars left in the box. Using addition and subtraction, we find that there are -11 chocolate bars left in the box. Using multiplication and subtraction, we find that there are 243 chocolate bars left in the box.
