1. Because in math, there are only 4 things you will ever do: Add, Subtract, Multiply, and/or Divide.
2. Learn math vocabulary (or terminology). Once you learn math terminology you will solve many of your math problems, i.e., if you were asked, "What is the 'PRODUCT' of 4 and 3?" Well, if you already know how to multiply and you have learned that the term "PRODUCT" is associated with multiplication and is simply the result of multiplying 4 and 3, then you would understand that the "PRODUCT" of 4 and 3 is 12. Simple, right?
3. Learn the ORDER of OPERATIONS (sometimes called operator precedence) in Algebra. The ORDER of OPERATIONS is a rule used to clarify unambiguously which procedures should be performed first in a given mathematical expression. By learning the ORDER of OPERATIONS, you will be able to solve some math problems that has numerous operations within the same problem.
For example, in mathematics multiplication is done before addition; in the expression 3 + 5 × 7, the answer is 38. Brackets, which have their own rules, may be used to avoid confusion, thus the preceding expression may also be rendered 3 + (5 × 7), but the brackets are not required as multiplication still has precedence without them.
4. Learn to master and/or at least learn when to use formulas. Also use charts and other learning tools and manipulatives to help you solve math problems. They help make math easy to understand. Hope this helps you to get over your fear of math!
