Since the signs are different, we need to find the difference in their absolute value. So, $8$ $–$ $5 = 3$ The sign of the resultant integer will be the sign of the integer with the highest absolute value. Here, 8 is the integer with the highest absolute value, and its sign is...
If the original value ofxwas negative, then−x, the opposite-signed version ofx, would have to be positive. For instance, if I start withx= −3, then−x= −(−3) = +3, which is positive. You can use the Mathway widget below to practice simplifying an absolute-value expressi...
What are pictograms in math? What is meant by algebraic expression? Explain with an example. Why are parentheses used in mathematics? Where does the parenthesis go on the equation 5x(3 + 2) - 2 + 5x^3 = 4 for it to be true. ...
Relative valuation models determine the value based on the observation of market prices of similar assets. For example, one way of determining the value of a property is to compare it with similar properties in the same area. Likewise, investors use theprice multiplescomparable public companies tra...
indicate those terms should be dealt with first in the order. For example, in the expression (3 + 4) x 5 the parentheses group the addition of 3 and 4, thus indicating that they should be added first then the sum multiplied by 5. The final answer to (3 + 4) x 5 is 7 x 5= ...
There are countless theorems in mathematics and, in some sense, the mathematician's job is to prove theorems. In mathematical analysis, there are a number of very important theorems about continuous functions that form the foundations of calculus. Some of these theorems are the mean value theorem...
In sports, too, negative numbers can be used to denote the scores of teams. One great example is golf. The golfer with the lowest score, which represents the least amount of strokes, wins! As you can see, there are many real-world applications of negative numbers. They may not be as ...
Interquartile is a term used in statistics. In particular, the interquartile range is one measure of the spread of a distribution. A distribution is a record of the values of some variable. For example, if we found the incomes of 100 people, that would be the distribution of income in ...
A Venn diagram in math can show how various sets of numerical data overlap with one another. To take a simple example, if one circle represents every number between 1 and 25 and another represents every number between 1 and 100 that is divisible by 5, the overlapping area would contain the...
For example, she has the opinion that every sequence of digits is a number. Although this might seem a bit careless, it turns out to be the initial spark and a driving force of the whole investigation. In the history of mathematics, the “naive” approach of putting difficulties with ...
