Left Section (k=2.5, m=4, n=12)

Step1: Evaluate 2km

Substitute values: $2 \times 2.5 \times 4$

Step2: Evaluate $\frac{m+n}{m}$

Substitute values: $\frac{4+12}{4}$

Step3: Evaluate $n-(m+k)$

Substitute values: $12-(4+2.5)$

Step4: Evaluate $3(m+n)$

Substitute values: $3 \times (4+12)$

Step5: Evaluate $m \cdot m \cdot m$

Substitute values: $4 \times 4 \times 4$

Step6: Evaluate $\frac{n \cdot n}{m}$

Substitute values: $\frac{12 \times 12}{4}$

Step7: Evaluate $\frac{kn}{5}$

Substitute values: $\frac{2.5 \times 12}{5}$

Step8: Evaluate $\frac{150}{km}$

Substitute values: $\frac{150}{2.5 \times 4}$

Right Section (d=10, u=7, e=3.2)

Step9: Evaluate $de$

Substitute values: $10 \times 3.2$

Step10: Evaluate $9du$

Substitute values: $9 \times 10 \times 7$

Step11: Evaluate $\frac{u \cdot u}{d}$

Substitute values: $\frac{7 \times 7}{10}$

Step12: Evaluate $d(e+5)$

Substitute values: $10 \times (3.2+5)$

Step13: Evaluate $\frac{500}{d \cdot d}$

Substitute values: $\frac{500}{10 \times 10}$

Step14: Evaluate $15(d-u)$

Substitute values: $15 \times (10-7)$

Step15: Evaluate $u-e$

Substitute values: $7 - 3.2$

Step16: Evaluate $\frac{ue}{eu}$

Substitute values: $\frac{7 \times 3.2}{3.2 \times 7}$

Answer:

Left Section Results:

• S. $2km = 20$
• H. $\frac{m+n}{m} = 4$
• E. $n-(m+k) = 5.5$
• A. $3(m+n) = 48$
• I. $m \cdot m \cdot m = 64$
• S. $\frac{n \cdot n}{m} = 36$
• O. $\frac{kn}{5} = 6$
• E. $\frac{150}{km} = 15$

Right Section Results:

• I. $de = 32$
