Question

Jayvon has 33.6 points in a competition. He loses 5.5 points,

Write and then evaluate an addition expression to determine Jayvon's current points.

Answer 1

33.6+(-5.5)=28.1

Explanation:

Since positive times negative is equal to negative, we can multiply -5.5 by an addition symbol, making it an addition problem, and making it the same expression.

To evaluate the expression, we can do 33.6-5.5.

When adding or subtraction decimals, write it stacked like a normal problem, and line up the decimal places, like so.

33.6-

5.5

Then you can subtract normally, getting 28.1
