786 × 3 + 786 × 7 = ____
786 × 10
Start with the expression:
\(786 \times 3 + 786 \times 7\)
Notice both terms have a common number \(786\). Factor it out (distributive property):
\(786 \times 3 + 786 \times 7 = 786 \times (3 + 7)\)
Add the numbers inside the brackets:
\(3 + 7 = 10\)
So we get:
\(786 \times (3 + 7) = 786 \times 10\)
Therefore, the simplified answer is:
\(786 \times 10\)
(If you want the final value: \(786 \times 10 = 7860\).)
