#binomials

PEMDAS may help in basic math, but don't forget FOIL for when you're multiplying binomials!

F - First! Do whatever step you want to first!

O - Outer! Go do your math out in nature! It helps to bring down the stress levels caused by math AND it's cooler to say a bear ate your homework than your dog.

I - Inner! Do some self reflection! Is this really what you want to be doing? Is math truly going to be your future? Why are you worried about binomials?

Multinomial coefficients and Pascal's Simplex

For binomials [ (a+b)ⁿ ] the use of Pascal's triangle is helpful. In Pascal's triangle each single row in the triangle defines the coefficients of binomials of each n-value.

For trinomials [ (a+b+c)ⁿ ] this pattern can be extended to a 3-dimensional Pascal's tetrehedron, where each level (and hence a complete triangle) in that tetrehedron defines the coefficients of trinomials of each value of n.

Latin name or scientific name, where do you stand?

Recently, the gentlefolk who oversee the Annals of Botany blog site and Mr Cuttings have been engaged in good old-fashioned healthy debate about what to call scientific binomials, those two word official names that every described organism has. And that debate has revolved around whether they should be referred to as ‘Latin names’ or as ‘scientific names’. One of the bilingual English and Latin…
