Because the census taker knew the total (from the number on the gate) but said that he had insufficient information to give a definitive answer, there must be more than one solution with the same total. Only two sets of possible ages add up to the same totals: A. 2 + 6 + 6 = 14 B. 3 + 3 + 8 = 14
The multiplication of whole numbers may be thought of as repeated addition; that is, the multiplication of two numbers is equivalent to adding as many copies of one of them, the multiplicand, as the quantity of the other one, the multiplier; both numbers can be referred to as factors.
So think of the next number after 14 that ends with 1, which is 21. After coming to the top of this column, start with the bottom of the next column, and travel in the same direction. The number is 8. So think of the next number after 21 that ends with 8, which is 28. Proceed in the same way until the last number, 3, corresponding to 63.
The sequence of numbers involved is sometimes referred to as the hailstone sequence, hailstone numbers or hailstone numerals (because the values are usually subject to multiple descents and ascents like hailstones in a cloud), [5] or as wondrous numbers. [6] Paul Erdős said about the Collatz conjecture: "Mathematics may not be ready for such ...
To find out your dog's "real" age, you need to find the natural logarithm of your dog's current age (that's where the calculator comes in handy), then multiply that number by 16 and add 31. Here's ...
Adopt one of eight lifestyle habits at age 40, and you could add 4.5 years to your life, a new study found. Add all eight, and you might live up to 24 years longer.
Scientists examined the lives of 700,000 U.S. veterans before predicting that people who adopted certain habits could live up to 24 years longer. Following these 8 habits may add 24 years to your ...
First multiply the quarters by 47, the result 94 is written into the first workspace. Next, multiply cwt 12*47 = (2 + 10)*47 but don't add up the partial results (94, 470) yet. Likewise multiply 23 by 47 yielding (141, 940). The quarters column is totaled and the result placed in the second workspace (a trivial move in this case).
