Mathematics is indeed a universal language. Even errors are universal. Here are the top ten errors in algebra which are beyond borders and colors.

#10. Squaring the negative. *A minus a squared unless it’s been snared: *

#09. Logarithms: *The log of the sum ain’t the sum of the log: *

#08. Shifting function: *Add to y go high, add to x go west: *

#07. Inequality: *Multiplying the inequality by a negative flips the inequality: *

#06. On exponents: *When in doubt, write it out: *

#05. Fractional exponent: *Don’t flip over the root. *

#04. Subtraction: *Don’t forget to share the minus and the negativity. *

#03. Cancellation: *Cancel factors, not individual terms. *

#02. Quadratics: *Remember exponents 2, answers 2. *

#01. Squaring: *Don’t forget to FOIL. *.

Here is one comment from YouTube viewer:

For all the idiots who say #10 and #2 contradict themselves are completely wrong.#10:-8^2 IS NOT (-8)^2. Without the parenthesis, -8^2 = (-1)(8)(8), which equals -64. Do you guys see it now? (-8)^2 = (-8)(-8) = 64, which is 100% correct. I see where you guys are coming from, but thats why its a top 10 mistake.#2:5*5 = 25, -5 * -5 = 25. What’s wrong? How does this contradict #10?

Do you agree? How would you explain to students that when they know that is the negative number 8?
