how do i make

4 6s equal 66
and
4 8s equal 640

To solve these puzzles, you need to find the mathematical operations or manipulations you can perform on the given numbers to make them equal the target numbers. Let's break it down step by step:

For the first puzzle, where you need to make 4 sixes equal 66:
1. Start by noting that you have 4 instances of the number 6.
2. One way to make 66 using these 6s is by using multiplication. Multiply 6 by 11 to get 66: 6 * 11 = 66. Therefore, the solution for the first puzzle is 6 * 11 * 1 * 1 = 66.

Now let's move on to the second puzzle, where you need to make 4 eights equal 640:
1. Similar to the previous puzzle, you have 4 instances of the number 8.
2. One way to make 640 using these 8s is also through multiplication. Multiply 8 by 10 four times to get 640: 8 * 10 * 10 * 10 * 10 = 640. Therefore, the solution for the second puzzle is 8 * 10 * 10 * 10 = 640.

In both cases, you can use the concept of multiplication to achieve the desired results. Remember to carefully examine the given numbers and think about the mathematical operations you can perform to reach the target numbers.

To make four 6s equal 66, you can use the following equation:

6 + 6 + 6 + 6 = 66

To make four 8s equal 640, you can use the following equation:

8 * 8 * 8 * 8 = 640

66 + 6 - 6 = 66

I don't know if you can include other numbers or not.

80 * 8/8 * 8 = 640

If you can't use other numbers, I hope my response gives you some ideas. Thanks for asking.
