2.1.2. \( -10+4(16-6) \div 2+4 \times 10 \)

1. Start with the expression \[ -10 + 4(16-6) \div 2 + 4 \times 10 \] 2. Simplify inside the parentheses: \[ 16 - 6 = 10 \] Now the expression becomes \[ -10 + 4 \times 10 \div 2 + 4 \times 10 \] 3. Perform the multiplication and division from left to right: - First, calculate \(4 \times 10\): \[ 4 \times 10 = 40 \] So, the expression is now \[ -10 + 40 \div 2 + 4 \times 10 \] - Next, divide \(40 \div 2\): \[ 40 \div 2 = 20 \] The expression simplifies to \[ -10 + 20 + 4 \times 10 \] - Then, calculate the remaining multiplication \(4 \times 10\): \[ 4 \times 10 = 40 \] Now, the expression becomes \[ -10 + 20 + 40 \] 4. Perform the addition sequentially: - First, add \(-10 + 20\): \[ -10 + 20 = 10 \] - Then, add the result to \(40\): \[ 10 + 40 = 50 \] The final result is \[ 50 \]
