Firstly, represent the 3₁₆ and E₁₆ as 2 four bit binary numbers (known as nibbles). Once we have this (0011 and 1110 respectively), we can then combine them back together, into one...

The area of a square is the length of one side squared (multiplied by itself), so for a square with side length 3, the area will be 3² or 3 x 3, which = 9. For a square with side length x, the ...

There are two easy ways to solve simultaneous equations. Substitution and elimination. In order to work with substitution we must rearrange one equation to be equal to either x or y. In this case, 2x+4y=8...

Equation 1: x+y=3Equation 2: -x+5y=-15Step 1: Check to see if any variables (x or y) can be eliminated. As there is x in equation 1 and -x in equation 2, x can be eliminated by adding the equations togeth...
