How to make 1-100 using only 4 5s
To make numbers from 1 to 100 using only four 5s, we can utilize mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. Here's a step-by-step guide on how to achieve it:
1. Start with the number 5 (the first 5).
2. Use exponentiation to get the other three 5s: 5^0 = 1. This gives us another 5, which we can use for concatenation later.
3. Create the numbers 10, 15, 20, 25, ..., up to 100 by using multiplication and addition with the four 5s.
- For example, to get 10, we can multiply the first 5 by 2: 5 * 2 = 10.
- To get 15, add the second 5 to the first 5: 5 + 5 = 10 + 5 = 15.
- Continue this process to create other numbers.
4. To reach numbers greater than 100, you can use concatenation. For instance, to get 55, combine the first 5 with the other three 5s: 5 + (5 * 5 * 5) = 5 + 125 = 130 - 75 = 55. Here, we used subtraction and multiplication in combination with concatenation to reach 55.
By employing these operations, you can create all numbers between 1 and 100 using only four 5s. Keep in mind that this method requires creativity in manipulating numbers and operations to achieve the desired results.
