Matt's Maths Christmas Jumper Explained!
<div>This is just the letter "M" (although often used for "mass" in physical equations)</div><div><br></div><div><br></div>
<div>This number (around 2.72) is the mathematical constant "e" which is known as "Euler's number" or the "exponential constant"</div> en.wikipedia.org e (mathematical constant) - Wikipedia
<div>This is the letter "R" squared, which can also be written as "RR"...</div>
<div>This is slightly trickier - you have "one divided by Y" in the brackets, which is raised to the power of "minus one". </div><div><br></div><div>The power of minus one is the same as writing "one divided by" everything in the brackets. </div><div><br></div><div>This is the same as "one divided by 'one divided by Y'", which works out to just "Y".</div> en.wikipedia.org Exponentiation - Wikipedia
<div>This is just the letter "X"</div><div><br></div><div>(although usually used as a variable to be calculated in algebra)</div>
<div>This is a way of rewriting Newton's second law of motion, where the force (F) on an object is equal to its mass (m) multiplied by its acceleration (a). </div><div><br></div><div>The formula is usually written as "F = m*a", but by dividing both sides of the equation by "a" then you get "F / a = m". </div><div><br></div><div>So, the force divided by acceleration equals "Mass".</div> en.wikipedia.org Newton's laws of motion - Wikipedia
