I have a table with an array of data, rows S, T, U, V and W all contain numbers.

I need a formula that will count how many times in my table, that the value of these 5 columns in any given row is Zero.
If S2, T2, U2, V2, and W2 all sum to Zero, I need the formula to count that

There are over 10,000 rows and the number varies everyday, it could be anywhere between 10,000 and 14,000.
