    1023 Words  | 5 Pages

    1.2.2 Rational numbers All the numbers that we use in our normal day-to-day activities are called Real Numbers. Real numbers are: Positive integers (1, 2, 3, 4, etc.) Fractions (1/2, 2/3, 1/4, etc). [The integers are really forms of fractions (1/1, 2/1, 3/1, etc.)] Negative numbers (-1, -3/4, etc.) Any numbers that can be written in the form a/b where a and b are whole numbers are called Rational Numbers. A rational number is a number that can be written as a ratio. That means it can be written

  • Mixed Numbers And Subtracting Like And Unlike Denominators

    467 Words  | 2 Pages

    The third main idea is mixed numbers and adding and subtracting like and unlike denominators. When adding mixed numbered fractions with the same denominator you add the whole numbers like normal and add the fractions like normal remembering to keep the denominator. For example, 2 ⅔ + 1 ⅓ = 2 + 1 = 3 and then 2 +1 for the numerators keeping the denominator a 3 gives you 3 3/3 or 4. In the denominators are not the same you leave the whole number alone and adjust the fractions like you did before. For

  • Complex Numbers: Rafael Bombelli's Life And Work

    968 Words  | 4 Pages

    Complex numbers were first encountered by the ancient Greeks and the ancient Egyptians through their applications of architecture. When dealing with a negative square root in the calculation of the volume of a square pyramid, the famous mathematician Heron changed a negative 63 to a positive 63. Diophantus discarded all negative solutions to his quadratic equations. It was not until Descartes that imaginary numbers were given their name. Imaginary numbers gave mathematicians a way to deal with the

  • Carl Sagan's Pi: The Transcendental Number

    Pi: The Transcendental Number The Greek symbol ԉ is used to denote an important mathematical constant. Simply put, it is the ratio of the circumference of a circle to its diameter. This ratio has been found to be constant, no matter what the size of the circle. Pi is an Irrational Number, which means that it can’t be written as a fraction. It is an unending decimal number. The number 2/7, when written in the decimal form is also unending. But after 6 digits, it repeats itself. It is 0.285714285714285714…

    her students multi-digit number comparison, included in comparing prices. For a student to be able to achieve number comparison, several math concepts have to be understood and demonstrated by the student. Comparing multi-digit numbers as well as decimal placement can be very challenging to teach. Not only do students have to recognize the magnitude of the price on the tag, they have to be able to locate the item in the store, and also be able to compare values of numbers. This can all be hard to

    compute mathematical operations but explain their reasoning and justify why using certain visual strategies such as number lines, number bonds and tape diagrams, aid in the computation of problems. When encountering mixed numbers, students may choose to use number bonds to decompose the mixed number into two proper fractions. This requires conceptual understanding that a mixed number is a fraction greater than one and can be decomposed into smaller parts. At the beginning of the lesson, students are

    in barcode numbers. The majority of products that you can buy have a 13-digit number on them, which is scanned to get all the product details, such as the price. This 13-digit number is referred to as the ‘GTIN-13’ where ‘GTIN’ stands for Global Trade Item Number. Error control is used in barcodes because without it, there would be so many errors and people would end up being charged for the wrong products. Sometimes when a barcode is being scanned, the scanner won’t read the number and therefore

    Introduction Place value is one of the cornerstones of our number system. Therefore, developing a robust, conceptual understanding of this topic is vital. If this is not achieved and if focus is placed on short-term performance or procedural knowledge, progress in mathematics is likely to be delayed (Department of Education WA, 2013a). Green (2014) upholds this belief as she describes seeing maths as more than just a list of rules to be memorised. Instead, mathematics should allow children to make
