The student is adding 1.347 and 3.68 which is the same as 3.680
The result cannot be 50.27 because 7 is the third digit after the decimal point, not the second. Also 8 + 4 = 12 which implies that 2 is the second digit after the decimal point in the result not the first. Again, 6 + 3 + 1 = 10 making 0 the first digit after the decimal and the number before the decimal is 5.
Apart from this, the student is adding small numbers like 1.347 and 3.68, the answer is a number around 5 not a large number like 50.
The result the students gets by adding 1.347 and 3.68 using a calculator is wrong.
No because there is no way you can add 1 and 3 and end up with 50
Without adding the numbers itself, 1.347 + 3.68 can not equal 50.27 because you have to line up the decimals before you add. Furthermore, if you rounded the numbers to the nearest whole number, 1+4=5. The answer should be around 5 not 50.27.
