Question 1

If @=H, #=E, $=A, ... then decode: '@#$%&'
Reverse mapping: @#$%& → HEART = HEART
reverse, decoding

Question 2

Using the symbol matrix: E → = | F → # | A → & | D → * | G → $ Code the word: 'ADAD'
Using matrix: A→& → D→* → A→& → D→* = &*&*
matrix, mapping

Question 3

If +=#, -=~, *=@, /=%, then evaluate: 1 ~ 3 @ 1
Decode symbols: 1 ~ 3 @ 1 → 1 - 3 * 1 = -2
arithmetic, operations

Question 4

If letters at even positions (1-based) = @, odd positions = #, then 'INTELLIGENCE' = ?
Alternating pattern: positions 1,3,5,7... = @, positions 2,4,6... = # → @#@#@#@#@#@#
pattern, position

Question 5

Using the symbol matrix: B → ? | A → @ | C → ! | D → & | G → + Code the word: 'CBDG'
Using matrix: C→! → B→? → D→& → G→+ = !?&+
matrix, mapping

Question 6

If @=M, #=O, $=U, ... then decode: '@#$%&'
Reverse mapping: @#$%& → MOUSE = MOUSE
reverse, decoding

Question 7

Using the symbol matrix: B → % | H → + | F → & | A → ! | E → $ Code the word: 'BEB'
Using matrix: B→% → E→$ → B→% = %$%
matrix, mapping

Question 8

If +=*, -=%, *=$, /=@, then evaluate: 10 % 12 * 7
Decode symbols: 10 % 12 * 7 → 10 - 12 + 7 = 5
arithmetic, operations

Question 9

If first and last letters = &, others = *, then 'SCIENCE' = ?
First-last special: S(first)=&, E(last)=&, middle letters=* → &*&
pattern, position

Question 10

If +=^, -=~, *=#, /=&, then evaluate: 6 & 5 ~ 3
Decode symbols: 6 & 5 ~ 3 → 6 / 5 - 3 = -2
arithmetic, operations

Question 11

If A=@, E=#, G=5, M=0, then 'GAME' is coded as?
Applying symbol substitution: G→5 → A→@ → M→0 → E→# = 5@0#
substitution, basic

Question 12

If @=B, #=R, $=A, ... then decode: '@#$%&'
Reverse mapping: @#$%& → BRAIN = BRAIN
reverse, decoding

Question 13

Using the symbol matrix: G → # | F → ? | B → ! | C → $ | H → = Code the word: 'BGFFH'
Using matrix: B→! → G→# → F→? → F→? → H→= = !#??=
matrix, mapping

Question 14

If A=@, I=$, B=1, N=!, R=+, then 'BRAIN' is coded as?
Applying symbol substitution: B→1 → R→+ → A→@ → I→$ → N→! = 1+@$!
substitution, basic

Question 15

If first and last letters = &, others = *, then 'ARTIFICIAL' = ?
First-last special: A(first)=&, L(last)=&, middle letters=* → &&
pattern, position

Question 16

If Layer 1: Letters → position numbers (A=1, B=2...), Layer 2: Numbers → symbols (1=@,2=#,3=$,4=%,5=&,6=*,7=+,8==,9=!,0=?), then code 'CODE'
Layer 1: CODE → C=3, O=15, D=4, E=5 = 31545
Layer 2: 31545 → $@&%&
multilayer, complex

Question 17

If @=S, #=O, $=U, ... then decode: '@#$%&'
Reverse mapping: @#$%& → SOUND = SOUND
reverse, decoding

Question 18

If vowels = @, even position consonants = #, odd position consonants = *, then 'PRINTER' = ?
Position-wise coding: P(pos 1, even)→#, R(pos 2, odd)→*, I(vowel)→@, N(pos 4, odd)→*, T(pos 5, even)→#, E(vowel)→@, R(pos 7, even)→# = #*@*#@#
conditional, rules

Question 19

If Layer 1: Letters → position numbers (A=1, B=2...), Layer 2: Numbers → symbols (1=@,2=#,3=$,4=%,5=&,6=*,7=+,8==,9=!,0=?), then code 'DATA'
Layer 1: DATA → D=4, A=1, T=20, A=1 = 41201
Layer 2: 41201 → %@#?@
multilayer, complex

Question 20

If Layer 1: Vowels=@, Consonants=#, Layer 2: @=1, #=2, then code 'PAGE'
Layer 1: PAGE → #@#@
Layer 2: #@#@ → 2121
multilayer, complex
