Calculator

Calculator is a Quirk used by Takumi Saiba.

Ability
Calculator allows its user to perform any mathematical equation instantaneously, as long as the user understands the mathematical concepts involved.

Calculator is ineffective if the equation contains a mathematical concept or operation that is either impossible, or unknown to the user. For example, Calculator will not provide an answer to zero divided by zero.

Awakened Form
After awakening, the user gains the ability to calculate the mathematical aspect of everything, even without quantifying the exact values. This allows them to accurately estimate and predict actions in the future, as well as calculating the optimal transfer of energy and momentum.

Limitations
Calculator is ineffective if the equation contains a mathematical concept or operation that is either impossible, or unknown to the user. For example, Calculator will not provide an answer to zero divided by zero.

Drawbacks
Overuse may cause lasting mental trauma for the user. Additionally, they may develop a form of Savant Syndrome, where they lose their ability to grasp spoken language, and can only communicate with numbers.

Weaknesses
Calculator has limited capability in situations unfamiliar to the user, or with either too many or too little calculable factors.
