Windows 10: Calculator gives wrong answer

I type the following into Calculator:

4 x 0.25 + 2 x 0.5

I get the answer:

1.5

This is wrong. The answer should be 2. I have no Feedback Hub to report this.

Windows Calculator gives wrong answer

When I use my keyboard to enter a problem the calculator gives the wrong answer. Sometimes it is only off by 5 percent but still off. It is usually off by 30-50 percent. When I use google's calculator I do not have this problem at all. Pls help I require
the calculator often and using the mouse doubles the time it should take to complete simple calculations.

 

CALCULATOR GIVES WRONG RESULT

The use of some simple calculators precludes the use of order of operations and the use of the %. The coding is correct for its intended use although most folks find it very irritating.

Use the percentage button (%) in order to find the result of an operation as a percentage. For instance, if you wanted to know what 10 times 10 percent was, you would press 10 * 10 %, and you would receive the answer "1.

The answer "1", is the percentage. If you want to multiply by a percent then you need to multiply by a decimal equivalent.
