Which of the following MS-EXCEL formulas are equivalent to each other? Choose the correct answer from the options given below:

The formulas that add all four cells A3, A4, A5 and A6 are equivalent, namely the plus expression, the range sum and the listed-cells sum.

Statement 1 adds A3 plus A4 plus A5 plus A6 directly, giving the total of the four cells.

Statement 2 uses the colon range A3 to A6, which means every cell from A3 down to A6, the same four cells.

Statement 4 lists the four cells separated by commas, again totalling exactly A3, A4, A5 and A6.

Statement 3 with SUM of A3 and A6 adds only the two named cells A3 and A6, skipping A4 and A5, so it differs.

A colon means a continuous range while a comma means only the specific cells named.
