Question

380÷20×4-3×(27÷3+17÷17)+56÷(72-58)

Answer 1

380/20*4=76
3*(27/3+1)=30
56/14=4
76-30+4=50
50

Answer 2

Let's solve the expression step by step following the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction):

1. Solve within parentheses/brackets:
   • $27 \div 3 + 17 \div 17$ = $9 + 1$ = $10$
2. Continue solving within parentheses/brackets:
   • $72 - 58$ = $14$
3. Divide and multiply from left to right:
   • $380 \div 20$ = $19$
   • $4 \times 4$ = $16$
   • $56 \div 14$ = $4$
4. Perform addition and subtraction from left to right:
   • $19 \times 16$ = $304$
   • $3 \times 10$ = $30$
   • $4 - 30$ = $-26$
   • $304 - 26$ = $278$

So, the result of the expression $380 \div 20 \times 4 - 3 \times (27 \div 3 + 17 \div 17) + 56 \div (72 - 58)$ is $278$.
