The biggest number Tony can make using the numbers 10, 1, 6, and 8 is:

[(10 / 1) x 8] = 80

To arrive at this number, Tony first divides 10 by 1 to get 10, then multiplies that result by 8 to get 80. This is the biggest number he can make using the given numbers and following the given rules.

Apologies for the mistake. Let's try a different approach to find the biggest number Tony can make using the numbers 10, 1, 6, and 8.

We can try the following calculation:

[(10 + 1) x 8] = 88

To arrive at this number, Tony first adds 10 and 1 to get 11, then multiplies that result by 8 to get 88. This is the biggest number he can make using the given numbers and following the given rules.

I apologize for the errors in my previous responses. Let's try a different approach to find the biggest number Tony can make using the numbers 10, 1, 6, and 8.

One possible way to achieve the biggest number is as follows:

(10 x (8 + 6)) - 1 = 189

In this calculation, you first add 8 and 6 to get 14. Then, you multiply 10 by 14 to get 140. Finally, you subtract 1 from 140 to get 189, which is the biggest number Tony can make using the given numbers.
