Q. {[7⋅(2+1)−2⋅3]:(1+2)}−[(3⋅2+5)−10] \{[7 \cdot(2+1)-2 \cdot 3]:(1+2)\}-[(3 \cdot 2+5)-10]
  1. Simplify First Bracket: Simplify the expression inside the first set of brackets.\newlineCalculation: 7×(2+1)−2×3=7×3−6=21−6=157\times(2+1)-2\times3 = 7\times3-6 = 21-6 = 15
  2. Simplify Denominator Parentheses: Simplify the expression inside the first set of parentheses in the denominator.\newlineCalculation: 1+2=31+2 = 3
  3. Divide First Bracket Result: Divide the result of the first bracket by the result of the parentheses.\newlineCalculation: 153=5\frac{15}{3} = 5
  4. Simplify Second Bracket: Simplify the expression inside the second set of brackets.\newlineCalculation: (3×2+5)−10=6+5−10=11−10=1(3 \times 2 + 5) - 10 = 6 + 5 - 10 = 11 - 10 = 1
  5. Subtract Second Bracket Result: Subtract the result of the second bracket from the result of the division.\newlineCalculation: 5−1=45-1 = 4
