To solve the expression \((17 \times 23) + (144 / 12) - 89\), we will follow these steps: 1. Calculate \(17 \times 23\) 2. Divide \(144\) by \(12\) 3. Substitute the results from steps 1 and 2 into the expression 4. Perform the arithmetic operations Let's start with step-by-step calculations: 1. **Calculate \(17 \times 23\):** \[ 17 \times 23 = 17 \times (20 + 3) = (17 \times 20) + (17 \times 3) \] Now calculate each term: \[ 17 \times 20 = 340 \] \[ 17 \times 3 = 51 \] So, \[ 17 \times 23 = 340 + 51 = 391 \] 2. **Calculate \(144 / 12\):** \[ 144 / 12 = 12 \] 3. Now substitute the results from steps 1 and 2 into the expression: \[ (17 \times 23) + (144 / 12) - 89 = 391 + 12 - 89 \] 4. Perform the arithmetic operations in the expression \(391 + 12 - 89\): \[ 391 + 12 = 403 \] Then, \[ 403 - 89 = 314 \] So, the final answer is: \[ \boxed{314} \]
