How can you decide if the sum of two numbers is positive negative or zero without calculating the sum?
The sum of two negative numbers is positive and the sum of two negatives is negative. If you have both positive and negative numbers the sum can be either so look at the absolute value. If the negative number has a greater absolute value, the sum is negative. If the positive number has a greater absolute value the sum is positive. If the absolute values are equal, the sum is zero.
How do you find the absolute value of 1.5?
To find the absolute value of 1.5, you simply ignore the negative sign, if any, and take the positive value. Since 1.5 is already a positive number, its absolute value is 1.5. The absolute value function essentially returns the distance of a number from zero on the number line, regardless of its sign.
What are 2 absolute values of 4?
the only absolute value would be 4, as the absolute value is the space that the number is away from zero. Both positive and negative four would equal four. On the other hand, if the negative sign was outside the absolute value ( -|4| ), then the number would be negative.
How do you get rid of absolute value in math?
You consider both cases, then the variable is positive and when it is negative. For example, |x|
What is the absolute value of a number?
Its distance from zero, always a positive number. The absolute value of a positive number is that number. The absolute value of a negative number is its positive equivalent. Usually denoted by vertical bars |n| The absolute value of both 7 and -7 is 7 |-7| = 7 |7| = 7 * * * * * Minor error above: the absolute value of 0 is 0, so not "always a positive number".
