area= $$\sqrt{s(s-a)(s-b)(s-c)}$$, Where, s is the semi perimeter and is calculated as s $$=\frac{a+b+c}{2}$$ and a, b, c are the sides of a triangle. As we remember from basic triangle area formula, we can calculate the area by multiplying triangle height and base and dividing the result by two. Pythagoras Theorem def... | {} |

# Shared entanglement to copy orthogonal states
Assume that Alice and Bob are allowed to share entanglement and are spatially separated. Alice is given an unknown state and asked to measure this in the computational basis to obtain $$\vert 0\rangle$$ or $$\vert 1\rangle$$. Is there some way for Bob to also have a copy... | {} |

The types and amounts of metals in the water therefore heavily influence the selection of an AMD treatment system. However, before the onset of ferric precipitation, the ferrous iron has to be oxidised to the ferric state, usually by bubbling air through the acid mine drainage solution. Usually groundwater has a low ox... | {} |

# Primitive recursion example
If we want to show primitive recursion for

Also, to show that x monus y = (x-y) if x >= y and 0 otherwise, where we have the ... | {} |
