Add four operation symbols 23 4 5 6 7 1 = 51 to the formula
2-3+4+5+6*7+1=51
Use 24 point algorithm, 2.6, 9, - 9 each number only once, carry out + 1_ /* to make the result equal to 24, the method should be adopted
2×[9-6-(-9)]＝24
9×[2-6/(-9)]＝24
4.5.9.11 equals 24
How do these four numbers equal 24 You can only add, subtract, multiply and divide
4.5.9.11 which of these four numbers can be equal to 24? I really have nothing to say
(- 24 9 / 4) + 16 4 / 5 =?, what is it
=(- 29 and 9 / 20)
