Rules for adding and subtracting integers

What is the first step in solving this problem?

-3 + 5 =

• Add the absolute value of both integers

• The answer gets the common sign of both integers

• The answer gets the sign of the biggest absolute value

• Look at the signs. Are they the same or different?

• Subtract the smaller absolute value from the larger absolute value.

What is the second step in solving this problem?

-3 + 5 =

• Add the absolute value of both integers

• The answer gets the common sign of both integers

• The answer gets the sign of the biggest absolute value

• Look at the signs. Are they the same or different?

• Subtract the smaller absolute value from the larger absolute value.

What is the last step in solving this problem?

-3 + 5 =

• Add the absolute value of both integers

• The answer gets the common sign of both integers

• The answer gets the sign of the biggest absolute value

• Look at the signs. Are they the same or different?

• Subtract the smaller absolute value from the larger absolute value.
