Jinsi ya Kuzidisha Arrays na Kisha Kujumlisha (SUMPRODUCT) kwenye Excel

SUMPRODUCT ni function yenye nguvu ya Excel inayokuwezesha kuzidisha arrays mbili au zaidi kisha kujumlisha matokeo. Ni muhimu kwa budgeting, sales calculations, na data analysis ambapo unataka kupata total weighted values kwa haraka na usahihi.

🔹 Kutumia SUMPRODUCT Function

Formula:

=SUMPRODUCT(array1, array2, ...)


Maelezo:

array1, array2 → Arrays (rows au columns) unazotaka kuzidisha

Excel inazidisha kila element ya array1 na element ya array2 kisha inazijumlisha

Mfano:

Quantity Unit Price
10 5
20 3
15 4

Formula: =SUMPRODUCT(A2:A4, B2:B4) → Matokeo: 155

Hapa, Excel inafanya: (10*5) + (20*3) + (15*4) = 50 + 60 + 60 = 170

🔹 Kutumia SUMPRODUCT kwa Conditions

Unaweza pia kutumia SUMPRODUCT kwa conditional calculations:

=SUMPRODUCT((A2:A10)*(B2:B10)*(C2:C10="Apple"))


Hapa, Excel inazidisha quantities na prices tu ikiwa product ni "Apple"

🔹 Tips za Kutumia SUMPRODUCT

SUMPRODUCT inasaidia kufanya weighted sums, totals with conditions, na complex calculations

Hakikisha arrays zina dimension sawa, vinginevyo Excel itatoa error

Changanya SUMPRODUCT na IF, logical expressions, na ROUND kwa advanced calculations
