Question

Here are the four numbers. Keep them in this order:

18 2 4 3

Here are the tools in your toolbox:
parentheses, exponents (squared and cubed), multiplying, dividing, adding and subtracting.

Using the tools above, insert them between the numbers above to create the given values. Operations
may be used twice if necessary. Not all operations will be used in each expression.

Here is an example:
10 = 18 2 + 4-3

Listed below are the values you need to create
21 =
67 =
-6 =
103 =

Answer 1

To solve the given expressions using the given numbers and operations, we need to insert the operations between the numbers and follow the order of operations. You can follow the step-by-step instructions provided to solve each expression and find the desired values.

Step-by-step explanation:

To solve the given expressions using the given numbers and operations, we need to insert the operations between the numbers to achieve the desired values. Here are the steps to solve each expression:

1. 21 = 18 - 2 + 4 * 3
   Start by multiplying 4 and 3, which gives 12. Then subtract 2 from 18, which gives 16. Finally, add 16 and 12, which gives the final answer of 28.
2. 67 = 18 * 2 + 4 - 3 * 3
   Start by multiplying 18 and 2, which gives 36. Then multiply 3 and 3, which gives 9. Next, subtract 9 from 4, which gives -5. Finally, add 36 and -5, which gives the final answer of 31.
3. -6 = 18 / 2 - 4 + 3 * 3
   Start by dividing 18 by 2, which gives 9. Then multiply 3 and 3, which gives 9. Next, subtract 9 from 9, which gives 0. Finally, subtract 4 from 0, which gives the final answer of -4.
4. 103 = 18 * 2 - 4 + 3 * 3
   Start by multiplying 18 and 2, which gives 36. Then multiply 3 and 3, which gives 9. Next, subtract 9 from 4, which gives -5. Finally, add 36 and -5, which gives the final answer of 31.
