... Let the centres of the circles be B and C and the point of contact of the tangent line from B to the circle with centre C be A. Thus, ∠CAB = 90o using properties of tangents to a circle. Since the sides of right-angled triangle ABC are in the ratio of 1: 2: 3, ∠B = 30o and ∠C = 60o. The area of the ...

... Generally, the same rules apply to numbers expressed in scientific notation: When you write numbers in scientific notation, only the part before the multiplication sign is counted in the significant figures. For example: 0.00012 has two significant digits becomes 1.2×10−4 23900 has three significant ...

... Two numbers from different rows cannot be friends since their largest digits are different. Two numbers in the same row are friends if and only if they are adjacent. There are 2i − 1 numbers in the ith row. So we can take at most i numbers from the ith row without having an adjacent pair. This is on ...

Elementary arithmetic
Elementary arithmetic is the simplified portion of arithmetic that includes the operations of addition, subtraction, multiplication, and division. It should not be confused with elementary function arithmetic.Elementary arithmetic starts with the natural numbers and the written symbols (digits) that represent them. The process for combining a pair of these numbers with the four basic operations traditionally relies on memorized results for small values of numbers, including the contents of a multiplication table to assist with multiplication and division.Elementary arithmetic also includes fractions and negative numbers, which can be represented on a number line.
