In collections Place Value

This example demonstrates the subtraction algorithm by comparing steps and visualizing the process. It involves core math concepts like place value, borrowing, and algorithmic steps. Constructed using GeoGebra commands like Textfield and Sequence, featuring objects such as m_2, base, tens_2, m, etc. Suitable for middle elementary students or beginners learning subtraction principles.

GeoGebra Commands & Parameters

Textfield(base) → inputBox1
Sequence(Sequence[(t + 10, o), o, 1, base], t, 1, tens_2) → list_4
Sequence(Sequence[(t, o), o, 1, base], t, 1, tens) → list2
Sequence((tens + 1, o), o, 1, ones) → list1
Sequence((tens_2 + 11, o), o, 1, ones_2) → list3
Sequence(Sequence[Sequence[(((h - 1) * 10) + t, o), o, -11, base - 12], t, 1, base], h, 1, hunds_{sum}) → list_{sum3}
Sequence(Sequence[((hunds_{sum} * 10) + t, o), o, -11, base - 12], t, 1, tens_{sum}) → list_{sum2}
Sequence(((hunds_{sum} * base) + tens_{sum} + 1 + ((10 - base) * hunds_{sum}), o), o, -11, ones_{sum} - 12) → list_{sum1}
