If you begin to solve problems by looking for clue words, you will find that those words often indicate an operation.
Learning how to solve problems in mathematics is knowing what to look for.
Math problems often require established procedures and knowing what procedure to apply.
Then she has $x-\frac\cdot x=\frac\cdot x$ pages left.
$\frac\cdot x-\frac\cdot x=90$ $\frac\cdot x=90$ $x=270$So the book is 270 pages long.
These techniques may involve reorganizing a problem into simpler terms, breaking a problem into steps, making a plan about how to proceed, determining the best way to solve a problem, pulling out key ideas, etc.
Being systematic in problem solving requires students to: Systematic problem solving often involves "step-wisdom," knowing that the best way to solve a particular problem may be to break it up into a series of logical steps, rather than to try to solve it all at once.
