Let’s solve each expression step by step, following the
order of operations (PEMDAS/BODMAS): Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right).
---
1. R: 168 – 79 + 10
→ Left to right since only addition and subtraction:
168 – 79 =
89
89 + 10 =
99
✔ Answer: 99 → Letter R
---
2. S: 6 × (51 + 47)
→ First, parentheses:
51 + 47 =
98
→ Then multiplication:
6 × 98 =
588
✔ Answer: 588 → Letter S
---
3. T: 200 + 20 ÷ 2
→ Division first:
20 ÷ 2 =
10
→ Then addition:
200 + 10 =
210
✔ Answer: 210 → Letter T
---
4. E: 8 × 25 ÷ 5
→ Left to right for multiplication/division:
8 × 25 =
200
200 ÷ 5 =
40
✔ Answer: 40 → Letter E
---
5. E: 16 + 37(12 + 44)
→ First, parentheses:
12 + 44 =
56
→ Then multiplication:
37 × 56 — let’s compute that:
37 × 56 = 37 × (50 + 6) = (37×50) + (37×6) = 1850 + 222 =
2072
→ Then addition:
16 + 2072 =
2088
✔ Answer: 2088 → Letter E
*(Note: There are two "E" boxes — this is fine; both get the same letter.)*
---
6. C: 532 – ¼ × (77 + 23)
→ Parentheses first:
77 + 23 =
100
→ Then multiplication:
¼ × 100 =
25
→ Then subtraction:
532 – 25 =
507
✔ Answer: 507 → Letter C
---
## Now, match answers to letters in the table:
The table at the bottom has these answer slots:
| | | | | | |
|-----|-----|-----|-----|-----|-----|
| 588 | 2,088 | 507 | 99 | 40 | 210 |
We now assign the
letter associated with each answer:
-
588 → S
-
2,088 → E
-
507 → C
-
99 → R
-
40 → E
-
210 → T
So the riddle answer is:
S E C R E T
