To evaluate integer questions that involve multiple signs:
... The addition of integers can be shown by moves on a number line. - Start at the first integer - Move to the right for positive integers - Move to the left for negative integers To subtract an integer, add its opposite. Example 1: Evaluate. a) (+3) + (+4) b) (-3) + (-4) c) (+3) + (-4) d) (-3) + (+4) ...

Physics 12 - Course Assessment Assignment
... By lining up the object with the scale on the ruler, we can see that it is longer than 9 cm but shorter than 10 cm. Therefore, we can record with certainty that the object measures between 9 and 10 cm. We can also see that the object is greater than 9.5 cm and less than 9.7 cm. It looks pretty close ...

1.1 Real Numbers & Number Operations
... Examples of Real numbers • Whole numbers: 0, 1, 2, 3 (counting #s) • Integers: -2, -1, 0, 1, 2 (+ & - whole #s) • Rational numbers: a # that can be written as a fraction. When written as a decimal, they terminate or repeat. ½, 1/3, 4/5, 7/9 • Irrational numbers: real #s that are not rational such a ...

Elementary mathematics
Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
