The Whopper is equal to $$\underbrace{10\ \&\ 10\ \&\ 10\cdots10\ \&\ 10\ \&\ 10}_{\text{100 10's}}$$ = $$\lbrace 10,100 / 2 \rbrace$$ using the array of operator and BEAF.[1] The term was coined by Cookie Fonster. The number is named after the hamburger sold by Burger King.

Computation

The Whopper can be computed in the following process:

• $$a_1=10$$
• $$a_2=10\text{&}10=\lbrace10,10(1)2\rbrace$$ (iteral)
• $$a_3=10\text{&}10\text{&}10$$ (lineatrix)
• $$a_4=10\text{&}10\text{&}10\text{&}10$$
• etc.
• In general, $$a_{n+1} = a_n \text{&} 10$$.
• Then, the Whopper is equal to $$a_{100}$$.

Approximations

Since it is not defined by now, the following approximation is just an expected value:

Notation Approximation
Bird's array notation $$\{10,10 [1 [1 \backslash_{98} 1,2 \backslash_{99} 2]_1 2] 2\}$$
Fast-growing hierarchy $$f_{\theta(\Omega_{98}^{\omega})}(100)$$
