range is how wide the setspans, or just the difference between the smallest number and the biggest number. mean, (sum)/(number of items in set) add all number and divide the total number we can get the mean or average number median, to find the median: identify the term precisely in...
The factors of 36 are of the form 2ᵃ x 3ᵇ, where ‘a’ can be 0, 1, or 2, and ‘b’ can be 0, 1, or 2. Therefore, there are 3 choices for ‘a’ and 3 choices for ‘b’. The total number of factors is the product ofone more than[#] each exponent in the prime...
Can I use the rules of exponents with numerical expressions, with rational exponents to write equivalent expressions, with rational exponents? Number lines: Can I determine absolute values or rational numbers on a number line? Can I determine the distance between two numbers on a number line? Can...
The construction of IEEE floating-point numbers implies that they’re also rational, so commonly used numbers such as π aren’t expressed exactly, and operations using them, such as sin(x), aren’t exact, either. Moreover, unlike with integers, the spacing between IEEE ...

NanoRoboMath, a digital game-based learning environment, was developed to enhance students' conceptual and adaptive rational number knowledge. In this paper, we tested the effectiveness of a preliminary version of the game with fifth and sixth grade primary school students (N=195) using a quasi-...

Behavioral economicscomes into play here. A player continues playing thelottery, either in hopes of a big gain that would eventually offset the losses or because the winning streak compels the player to keep playing. In both cases, it is not rational or statistical reasoning but the emotional ...
