1. Алгебра – это система правил, касающихся действий с числами. 2. В алгебре числа обозначаются буквами, а не цифрами. 3. Поскольку буквы обозначают числа, все законы арифметики годны для действий с буквами. 4. Знаки, которые обозначают действия с цифрами, также употребляются для букв. 5. Операции сложения, вычитания, умножения, деления, возведения в степень и извлечения корней называются алгебраическими операциями. 6. В алгебре мы применяем следующие знаки: плюс, минус, знак равенства, знак умножения, знак деления, скобки круглые, квадратные и фигурные, знак «больше, чем», знак «меньше, чем» и другие. 7. Алгебраическому выражению можно придать более простую форму путём приведения подобных членов. 8. Алгебраическая сумма нескольких одночленов называется многочленом. 9. Двучлен – это алгебраическое выражение, состоящее из двух членов, трёхчлен – алгебраическое выражение, состоящее из трёх членов.
