Explain why these sentences are not propositions: He is the quarterback of our football team. x + y = 17 x + y = 17. AB = BA A B = B A. Example 2.1.5 2.1. 5. Although the sentence “ x + 1 = 2 x + 1 = 2 ” is not a statement, we can change it into a statement by adding some condition on x x. Sorted by: 2. These are the quotient groups of R R or Q Q by the subgroup Z Z. Starting with real numbers or rational numbers, declare two numbers equivalent if their difference is an integer. The equivalence classes under that relation form a group, called the quotient group. Using set-theoretic notation, we say x ∼ y x ∼ y if x − y ∈ ...Reflection definition. In geometry, a reflection is a rigid transformation in which an object is mirrored across a line or plane. When an object is reflected across a line (or plane) of reflection, the size and shape of the object does not change, only its configuration; the objects are therefore congruent before and after the transformation.The letter E can have two different meaning in math, depending on whether it's a capital E or a lowercase e. You usually see the capital E on a calculator, where it means to raise the number that comes after it to a power of 10. For example, 1E6 would stand for 1 × 10 6, or 1 million. Normally, the use of E is reserved for numbers that would ...The symbol is called "becomes" and was introduced with IAL (later called Algol 58) and Algol 60. It is the symbol for assigning a value to a variable. One reads x := y; as "x becomes y". Using ":=" rather than "=" for assignment is mathematical fastidiousness; to such a viewpoint, "x = x + 1" is nonsensical.Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes.
