7+7+7+7+7+7+7+7 is the same as 7 multiplied by 8, so the answer is 56.
7+7+7+7=28
One way (there may be more) is: 77/7 + 7 + 7 + 7 + 7/7 + 7/7 +7/7 + 7/7 + 7/7 = 11 + 21 + 5 = 37
7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 = 732 = 1104427674243920646305299201
7 + (7/7) + (7 x 7) - 7 = 50
12
3, 6, 9, 12, 15 and so on.
60, 120, 180 and so on.
4, 8, 12, 16, 20, 24 and so on.
They are members of an infinite set of numbers of the form 42*k where k is an integer.
(7*7)-7+(7-7)+(7/7)=43(7*7)-(7+7)+(7/7)+7=43(7*7)+(7/7)-(7-7)-7=43(7*7)-7+(7/7)+(7/7)=43(7*7)+(7/7)+7-(7+7)=43(7*7)-(7-7)+7+(7/7)=43
............. .....777... ....7....... ...7......... ...7777.... ...7....7... ...7....7... ....777..... .............. Also: 7 - 7/7 And: 7/7 + 7/7 + 7/7 + 7/7 + 7/7 + 7/7
7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 or 7 x 14 = 98 Dont you have a calculator...?
7 + 7 ÷7 + 7 x 7 - 7 =7 + (7 ÷7) + (7 x 7) - 7 =7 + (1) + (49) - 7 =7 + 1 + 49 - 7 =50
1 = (7/7) x (7/7) 2 = (7/7) + (7/7) 3 = (7+7+7)/7 4 = 5 = 6 = ((7 x 7) - 7)/7 7 = 7 8 = ((7 x 7) +7)/7 9 = ((7+7)/7) +7 10 = Unsure on the others.
7+7+7+7+7+7+7+7+7=63
751 is the same as 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 x 7 = 1.2589255 x 1043
