According to the Institute for Healthcare Improvement (IHI), the National Patient Safety Foundation (NPSF) Lucian Leape Institute and NORC at the University of Chicago 41 percent of adults in the United States have experienced a medical error in their own care or in the care of someone close to them. A wrong diagnosis is the most commonly type of error reported.
Step-by-step explanation:
A math expression is anything where you take one or more numbers and add them, subtract them, multiply, divide, etc etc
For example, 2+3 is a math expression
To make it an algebraic expression, we replace one of the numbers with a variable. Often this is the letter x. So let's say we replace the 2 with x. That would have the expression turn into x+3. What we're saying is "some number plus 3"
Normally 2+3 = 5 which is a true equation. Replace the 2 with x and we have x+3 = 5. So we're saying "some number plus 3 is 5". You can guess and check to find that the "some number" has to be 2
--------------------------------------
In summary, the expression example was x+3 and the equation was x+3 = 5
Note: an equation is simply two expressions set equal to each other.
