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. .
