    Base Ten blocks for math. Virtual manipulatives for mathematics are digital representations of physical mathematics manipulatives used in classrooms. [1] The goal of this technology is to allow learners to investigate, explore and derive mathematical concepts using concrete models. [2] [3]

  3. Ternary computer - Wikipedia

    en.wikipedia.org/wiki/Ternary_computer

    Ternary computing is commonly implemented in terms of balanced ternary, which uses the three digits −1, 0, and +1. The negative value of any balanced ternary digit can be obtained by replacing every + with a − and vice versa. It is easy to subtract a number by inverting the + and − digits and then using normal addition.

    Wooden Dienes blocks in units of 1, 10, 100 and 1000 Plastic Dienes blocks in use. Base ten blocks, also known as Dienes blocks after popularizer Zoltán Dienes (Hungarian: [ˈdijɛnɛʃ]), are a mathematical manipulative used by students to practice counting and elementary arithmetic and develop number sense in the context of the decimal place-value system as a more concrete and direct ...

    Base Ten Blocks are a great way for students to learn about place value in a spatial way. The units represent ones, rods represent tens, flats represent hundreds, and the cube represents thousands. Their relationship in size makes them a valuable part of the exploration in number concepts.

    en.wikipedia.org/wiki/Ternary_numeral_system

    A ternary / ˈ t ɜːr n ər i / numeral system (also called base 3 or trinary [1]) has three as its base.Analogous to a bit, a ternary digit is a trit (trinary digit).One trit is equivalent to log 2 3 (about 1.58496) bits of information.

  7. Balanced ternary - Wikipedia

    en.wikipedia.org/wiki/Balanced_ternary

    In the balanced ternary system the value of a digit n places left of the radix point is the product of the digit and 3 n. This is useful when converting between decimal and balanced ternary. In the following the strings denoting balanced ternary carry the suffix, bal3. For instance, 10 bal3 = 1 × 3 1 + 0 × 3 0 = 3 dec

  8. Carry (arithmetic) - Wikipedia

    en.wikipedia.org/wiki/Carry_(arithmetic)

    The ten is moved from the next digit left, leaving in this example 3 − 1 in the tens column. According to this method, the term "borrow" is a misnomer, since the ten is never paid back. The ten is copied from the next digit left, and then 'paid back' by adding it to the subtrahend in the column from which it was 'borrowed', giving in this ...

  9. Positional notation - Wikipedia

    en.wikipedia.org/wiki/Positional_notation

    A three-digit, decimal numeral can represent only up to 999. But if the number-base is increased to 11, say, by adding the digit "A", then the same three positions, maximized to "AAA", can represent a number as great as 1330. We could increase the number base again and assign "B" to 11, and so on (but there is also a possible encryption between ...
