Find the matching trios. Read the mathematical idea in words in the first column. Find the same mathematical idea written in symbols in the second column. Find the answer in Column 3. Colour code each matching trio the same colour.

• Symbolic idea: $b - 5 = 22$
• Answer: $$b - 5 = 22$$ $$b = 22 + 5$$ $$b = \boxed{\textbf{27}}$$

• Symbolic idea: $15 + 6 + 9$
• Answer: $$15 + 6 + 9 = 21 + 9 = \boxed{\textbf{30}}$$

• Symbolic idea: $20 \times 8$
• Answer: $$20 \times 8 = \boxed{\textbf{160}}$$

• Symbolic idea: $48 \div 8$
• Answer: $$48 \div 8 = \boxed{\textbf{6}}$$

• Symbolic idea: $m - 8 = 3$
• Answer: $$m - 8 = 3$$ $$m = 3 + 8$$ $$m = \boxed{\textbf{11}}$$

• Symbolic idea: $13 \times 3$
• Answer: $$13 \times 3 = \boxed{\textbf{39}}$$

What are the numbers?"

• Symbolic idea: $a+b=29$
• Answer: Let the two consecutive numbers be $x$ and $x+1$. $$x + (x+1) = 29$$ $$2x + 1 = 29$$ $$2x = 29 - 1$$ $$2x = 28$$ $$x = 14$$ The numbers are 14 and $14+1=15$. The numbers are $\boxed{\textbf{14, 15}}$

• Symbolic idea: $25 - \cdot = 16$
• Answer: $$25 - x = 16$$ $$x = 25 - 16$$ $$x = \boxed{\textbf{9}}$$

• Symbolic idea: $a^2 = 169$
• Answer: $$a^2 = 169$$ $$a = \sqrt{169}$$ $$a = \boxed{\textbf{13}}$$

• Symbolic idea: $25 + (18 - 13)$
• Answer: $$25 + (18 - 13) = 25 + 5 = \boxed{\textbf{30}}$$

• Symbolic idea: $15 + (10 \times 100)$
• Answer: $$15 + (10 \times 100) = 15 + 1000 = \boxed{\textbf{1015}}$$

• Symbolic idea: $4^2 \times (3 \times 5)$
• Answer: $$4^2 \times (3 \times 5) = 16 \times 15 = \boxed{\textbf{240}}$$
