  2. Number sentence - Wikipedia

    en.wikipedia.org/wiki/Number_sentence

    Sometimes boxes or shapes are used to indicate unknown values. As such, number sentences are used to introduce students to notions of structure and elementary algebra prior to a more formal treatment of these concepts. A number sentence without unknowns is equivalent to a logical proposition expressed using the notation of arithmetic.

  3. Grid method multiplication - Wikipedia

    en.wikipedia.org/wiki/Grid_method_multiplication

    Mathematically, the ability to break up a multiplication in this way is known as the distributive law, which can be expressed in algebra as the property that a(b+c) = ab + ac. The grid method uses the distributive property twice to expand the product, once for the horizontal factor, and once for the vertical factor.
