Algebra is a branch of mathematics that is concerned with arithmetic operations using symbols. Algebra helps in the representation of problems or situations as mathematical expressions. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and divisio...
What Is Calculus?Calculus is a branch of mathematics that studies continuously changing quantities. Its devel-opment is credited to (归功于) two late 17th-century mathematicians, Gottfried Leibniz andIsaac Newton. Calculus is more or less a combination of algebra and geometry. If you are fa-...

The GRE test assesses the candidate’s basic arithmetic, geometry, and algebra command and college-level vocabulary and your ability to evaluate and analyze written...
In mathematical terms, “how much” is X. So, using your eighth-grade algebra (with modern help in the form of a calculator) to determine the value of X, start by multiplying $60,000 by 10. Do the same for 0.08. Now you have $600,000 = 0.8 of X. Multiply both by 10 again to...
