Tiger Algebra

Tiger Algebra provides an equation/problem box, Solve control and notation keyboards, with examples grouped by operation rather than only by expression. Its homepage distinguishes order of operations, LCM/GCF, linear equations, percentages, radicals and polynomial tasks, with Learn, Practice and Quiz routes. The linked order-of-operations lesson treats multiplication/division as equal-priority operations evaluated left to right, followed by addition/subtraction under the same rule; parentheses and powers come first. Preserve explicit grouping and signs in a longer input. The topic explanation is useful for comparing the intended procedure with a solver request, while the practice route provides a separate learning task.
