put the correct sign between numbers to give the given answer ...........?

Question

9 9 9 9 = 11
8 8 8 8 = 2
7 7 7 7 = 1
6 6 6 6 =37
5 5 5 5 =45

Answer 1

(9 + 9) / 9 + 9 = 11
(8 / 8 ) + (8 / 8) = 2
(7+7 ) / (7+ 7) = 1
6 x 6 + 6 / 6 = 37
(5 + 5) x 5 - 5 =45

I know some of the parentheses are unnecessary, but I thought it would make the answers more comprehensible.

Remember the Order of Operations:
Exponents
Parentheses
Multiplication and Division ( left to right)
Addition and Subtraction (left to right)

Answer 2

1+2-3-4+5-6-7-8+9=1

Answer 3

(9 + 9) / 9 + 9 = 11
(8 / 8 ) + (8 / 8) = 2
(7+7 ) / (7+ 7) = 1
6 x 6 + 6 / 6 = 37
(5 + 5) x 5 - 5 =45

Answer 4

The signs

multiplication = x

Division = /

Addition = +

Subtraction = -

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

(9 + 9)/9 + 9

(8/8) + (8/8 = 2

(7 + 7) / (7 + 7) = 1

(6 x 6) + 6 / 6 = 37

(5 + 5) + (5 - 5) = 45

Answer 5

7 / 7 + 7 - 7 = 1
6 * 6 + 6 / 6 = 37
8 / 8 + 8 / 8 = 2
55 - 5 - 5 = 45 (must there be a sign between each digit?)

Can't figure the 9's at the moment.

Answer 6

(9+9) / 9 + 9 = 11

8/8 + 8/8 = 2

7/7 + 7 - 7 = 1

6/6 + 6x6 = 37

(5 + 5) x 5 - 5 = 45

cool stuff!

Answer 7

Just to be a wise guy, you didn't say we couldn't use
signs on the right side of "=". So
9/9+9/9=1+1 .
Let "|" be a sign meaning juxtaposition, then
(6/6)|(6-6)=3+7.
Using the absolute sign "[...]" we have
55/55=[4-5]. Then there's
5+5+5+5=4*5
And 77/77=1 as does ((7/7)/7)7=1 and of course
(7*7)/(7*7)=1 and (7/7)/(7/7)=1 and
(7-7)+7/7=1
Using "^" for the exponential sign we have
7^7/7^7=1

Answer 8

Try this one
1 2 3 4 5 6 7 8 9=1

P.S. Can you use logic instead of guess work to solve it.
