• Subtopic: Numeration Rules The numeration figures must always be greater than 0, and the first figure must always be different from 0. • Subtopic: Equations and Calculations a: Given the equation $a + b + c = 12$. b: Given the equation $a + b + c = 19$. c: Calculate the value 21. d: If: $$ab \times m = 84$$ $$ab \times n = 39$$ Calculate $ab \times mn$. • Subtopic: Calculation Tasks a: Calculate the following: - $b56$ - $c78$ - $a56$ - $b23$ - $c12$ b: Calculate the following: - $ab - 1$ - $ab + 1$ - $ab + 5 - 1$ - $ab + 5 + 1$ c: Calculate the following: - $ab + 1$ - $ab - 1$ - $ab + 5 - 1$ - $ab + 5 + 1$ d: Calculate the following: - $ab \, c$ - $a \, b \, c$ - $a \, b \, c$ - $a \, b \, c$ e: Calculate the following: - $ab \, c$ - $a \, b \, c$ - $a \, b \, c$ - $a \, b \, c$
