Simplify the given expression. 189 ÷ 9 + 117 ÷ 13 × 5 − 12 of 4 + 9 × 7
81
Apply the BODMAS order, evaluating 'of' first, then division and multiplication, then addition and subtraction.
'12 of 4' means \(12 \times 4 = 48\).
\(189 ÷ 9 = 21\); \(117 ÷ 13 × 5 = 9 × 5 = 45\); \(9 × 7 = 63\).
The expression becomes \(21 + 45 − 48 + 63\).
\(21 + 45 = 66\); \(66 − 48 = 18\); \(18 + 63 = 81\).
Hence, the value of the expression is 81.
