Understanding Subtracting Integers with LCO

What is the main issue when trying to subtract positive integers from negative integers?

• The result is always zero.

• There are not enough positive integers to subtract.

• Negative integers cannot be subtracted.

• Positive integers become negative.

What is a zero pair in the context of integer operations?

• A pair of numbers that multiply to zero.

• Two negative numbers that add up to zero.

• A number and its opposite that sum to zero.

• Two positive numbers that add up to zero.

What does the 'L' in LCO stand for?

• Link

• Leave

• List

• Learn

How does the LCO strategy help in solving subtraction problems?

• It changes the problem into a multiplication problem.

• It simplifies the problem by removing integers.

• It converts the subtraction into an addition problem.

• It eliminates the need for zero pairs.

In the LCO method, what does the 'O' stand for?

• Operation

• Order

• Opposite

When using LCO, what should you do with the first term?

• Multiply it by two.

• Add a zero pair.

• Leave it unchanged.

• Change it to its opposite.

What is the result of 63 minus negative 38 using LCO?

What happens when you subtract a number from itself using LCO?

• The result is zero.

• The result is the number itself.

• The result is negative.

• The result is positive.

Why is it important to use LCO in integer operations?

• To make the problem more complex.

• To change the problem to multiplication.

• To avoid computational errors.

• To use a calculator.
