What is a word problem in mathematics?

• A problem that can be solved using only numerical calculations.

• A mathematical problem expressed in words, requiring the translation of the text into a mathematical equation to solve.

• A problem that involves only geometric shapes and figures.

• A question that has no definitive answer and is open to interpretation.

What is the process of subtraction in mathematics?

• Subtraction is the mathematical operation of taking one number away from another to find the difference.

• Subtraction is the process of adding two numbers together to get a sum.

• Subtraction is the method of multiplying a number by zero to get the original number.

• Subtraction is the technique of dividing a number by itself to find the quotient.

How can you identify keywords in a word problem that indicate addition or subtraction?
