9 + 9 + 9/9 + (9 x 9) = 100
As a solution to the four fours problem (using the number four no more than four times to come up with the solution, 31 is equal to (4!+4)/4+4!
To make 10 using five nines, you can use the following mathematical expression: (9/9) + (9/9) + (9/9) + (9/9) + (9/9) = 10. This equation involves dividing each nine by itself (which equals 1) and then adding these results together to reach a total of 10.
Well, honey, there are nine nines in a billion. Simple as that. Just count those zeros and you'll see it for yourself. Don't make it harder than it needs to be, darling.
Google "Four Fours" and you will find a number of solutions, presented more comprehensively than we can.
9 + 9 + 9/9 + (9 x 9) = 100
99/9=11
9=10
9 + 9 + (9/9) = 19
eleven to the power of eleven
5*4+3+2
99 + 9(9 - 9)= 99 + 90 = 99 + 1 = 100
To make 200 using four numbers between 1-9, you can use the following equation: (9 x 9) + (9 x 9) - (9 + 1) = 200. This equation breaks down to (81) + (81) - (10) = 200. By multiplying two nines together twice and subtracting the sum of 9 and 1, you can achieve the target number of 200.
(55 / 55) + (55 / 55) x 5 = 10
As a solution to the four fours problem (using the number four no more than four times to come up with the solution, 31 is equal to (4!+4)/4+4!
To make 10 using five nines, you can use the following mathematical expression: (9/9) + (9/9) + (9/9) + (9/9) + (9/9) = 10. This equation involves dividing each nine by itself (which equals 1) and then adding these results together to reach a total of 10.
You divide 7 by 4 which is 1.75.
