Skip Counting
... Cover over the 2s with counters (or masking tape, or sticky notes, or blobs of plasticine) up to 20. Ask your child to skip count in 2s (2, 4, 6, 8, etc) by looking at the ruler or tape measure and saying out loud the number hidden under the ...

INTEGERS 10 (2010), 423-436 #A36 POWERS OF SIERPI ´ B
... The definition of the (usual) Sierpiński numbers requires that k be odd. This is done to avoid the Fermat numbers. The only primes of the form 2m 2n + 1 (with m and n integers) are the Fermat primes. It is possible (as mentioned in the famous footnote of Hardy and Wright [11]) that there may be onl ...

... is a perfect square. That is, the square of another natural number. Every odd integer is the difference between two perfect squares (the square of an integer). If a, b are real numbers, then a 2 + b 2 ≥ 2ab. The sum of two rational numbers is rational. Let p ( x ) be a polynomial and A is the sum of ...

“sum” of an infinite series
... is complicated by the fact that both the last term and the number of terms change with n. It is best to rewrite such limits in a closed form in which the number of terms does not vary, if possible. To do this, we multiply both sides of the equation for the general term by 1/10 to obtain: ...

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.
