Hello, I have some other not so simple riddles, at least I can't figure them out, so not simple to me. Can anyone help?

Thanks in advance to anyone who can help!!!!

use six 3's to make 8

use six 1's to make 99

use six 9's to make 100

use five 2's to make 88

use six 5's to make 100

use six 3's to make 31

Also:

Add 1 line and 1 sign to make a true equation for 99=8

Add 2 signs to make a true equation for 35=18

Add 5 lines to make a type of vehicle for 1 1 1 1

Add 2 lines to make a true equation for 11=12

Thanks for any and all help you can provide, my brain can't take any more, hahahaha

Well, I got a couple of them:

use six 1's to make 99: 111-11-1 = 99
use five 2's to make 88: (22 + 22) x 2 = 88

use six 3's to make 31: (3/3)+ (3×3×3)+3=31

use six 5's to make 100: {[(5×5)-5]/5}×5×5=100

use six 3's to make 8: 3×3-(3/3)×(3/3)=8

use six 9's to make 100: (9×9) +(9+9) +(9/9)=100
Students: Are you brave enough to let our tutors analyse your pronunciation?
use six 3's to make 8 :

( 33/3 - 3 ) - ( 3 - 3 ) = 8 - 0 = 8

use six 1's to make 99 :

111 - 11 - 1 = 99

use six 9's to make 100 :

( 999 - 99 ) ÷ 9 = 900 ÷ 9 = 100

use five 2's to make 88 :

(22 + 22 ) ×2 = 88

use six 5's to make 100 :

(55 - 5) + ( 55 - 5 ) = 50 + 50 = 100

use six 3's to make 31 :

33 - ( 3/3 ) - ( 3/3 ) = 33 - 1 - 1 = 31

Yes ..

two more :

- use five 2's to make 88 :

[ ( 2 + 2 ) ! - 2 ] × 2 × 2 = (4! - 2) × 4 = ( 24 - 2 ) × 4 = 22 × 4 = 88

- use six 1's to make 99

(11 - 1 - 1 ) × 11 = 9 × 11 = 99

Site Hint: Check out our list of pronunciation videos.
Add 1 line and 1 sign to make a true equation for 99=8 :

9 + 9 = | 8 ---> 9+9 = 18

Add 2 signs to make a true equation for 35=18 :

3 + 5 = 1 × 8 ---> 3+5 = 1×8 = 8

Add 2 lines to make a true equation for 11=12 :

11 = 12 | ---> 11=12-1
Add 5 lines to make a type of vehicle for 1 1 1 1

The answer could be "VAN" ... 1/ 1=1 1\| Emotion: smile Works for me.

use six 3's to make 8 is 3+3+3/3+3/3=8

use six 1's to make 99 may be is 111-11-1=99

use six 9's to make 100 is 9x9+9+9+9/9=100

use five 2's to make 88

use six 5's to make 100 is (5+5)x(5+5)+5-5=100

use six 3's to make 31 is 3x3x3 +3+3/3=31
