How do you make a number with 4 4s?

When you first start out, the problem seems pretty simple. So, for example, 4 – 4 + 4 – 4 = 0. To make 1, you can do 4 / 4 + 4 – 4. In fact, you can make all the numbers up to about 20 using only the basic arithmetic operations of addition, subtraction, multiplication, and division.

How many numbers can you make between 0 99 using exactly four 4s and the operations $$?

Of the 320 ways the numbers can be combined, 15 result in division by zero. Many other results are outside the 0-99 range of interest. In total, there are 56 unique rational results.

How can you make a total of 100 by using 7 fours?

Using the numerals 1,7,7,7 and 7 (a “1” and four “7”s) create the number 100. As well as the five numerals you can use the usual mathematical operations +, −, ×, ÷ and brackets (). For example: (7+1) × (7+7) = 112 would be a good attempt, but not right, because it is not 100.

Can u solve this viral IQ test?

To get 5 for the first line, you add 1 to 1 times 4. Similarly, the second line would be 2 + 2(5) = 12. For the third line, add 3 + 3(6) to get 21. Using this method for the final line, add 8 + 8(11) to get a final answer of 96.

How can you make any number out of four 4s?
Here, things start to get more complicated, but the back half of the video explains how incorporating the log into the four 4s problem allows you to work out ways to make every number up to infinity. The solution, involving multiple logs and square roots, broke open this puzzle in the 1930s.
What’s the difference between four fours and four fours?
Additional variants (usually no longer called “four fours”) replace the set of digits (“4, 4, 4, 4”) with some other set of digits, say of the birthyear of someone. For example, a variant using “1975” would require each expression to use one 1, one 9, one 7, and one 5.
