Opposites, absolute values and comparing integers: 15 questions. A mark next to each answer shows if it is right. Reload the page for new numbers.
A) Write the opposite of each integer.
B) Write the absolute value.
C) Compare using the symbols <, > or =.
Opposites and absolute value
The opposite of a number is the same distance from 0 on the other side of the number line. The opposite of ${9}$ is ${-9}$, and the opposite of ${-51}$ is ${51}$.
The absolute value is the distance from 0, so it is never negative: ${\lvert 52 \rvert = 52}$ and ${\lvert -13 \rvert = 13}$. A minus in front of the bars stays: ${-\lvert -91 \rvert = -91}$.
Comparing
Work out each side first, then compare the two numbers. The absolute value of ${-34}$ is ${34}$, and the opposite of ${\lvert 17 \rvert}$ is ${-17}$, so ${34 > -17}$.
On the number line, the greater number is the one further to the right. Every positive number is greater than every negative number, and ${-60 > -77}$.
