Questions

  1. (−8) + 15 − (−3) = ?

  2. (−4) × 5 × (−2) = ?

  3. (−36) ÷ 4 = ?

  4. (−3) × (−3) × (−3) = ?

  5. It is −6 °C at night, and the temperature rises by 4 °C every hour. What is it after 3 hours, in °C?

Answer key

  1. 10 — −8 + 15 = 7; subtracting −3 is adding 3: 7 + 3 = 10.
  2. 40 — (−4) × 5 = −20; (−20) × (−2) = +40 (two negatives make a positive).
  3. -9 — 36 ÷ 4 = 9, and a negative divided by a positive is negative: −9.
  4. -27 — (−3) × (−3) = 9, and 9 × (−3) = −27.
  5. 6 — It rises 3 × 4 = 12 degrees: −6 + 12 = 6 °C.

प्रश्न

  1. (−8) + 15 − (−3) = ?

  2. (−4) × 5 × (−2) = ?

  3. (−36) ÷ 4 = ?

  4. (−3) × (−3) × (−3) = ?

  5. रात में तापमान −6 °C है और हर घंटे 4 °C बढ़ता है। 3 घंटे बाद तापमान कितना होगा, °C में?

उत्तर

  1. 10 — −8 + 15 = 7; −3 घटाना मतलब 3 जोड़ना: 7 + 3 = 10।
  2. 40 — (−4) × 5 = −20; (−20) × (−2) = +40 (दो ऋण मिलकर धन)।
  3. -9 — 36 ÷ 4 = 9, और ऋणात्मक ÷ धनात्मक ऋणात्मक होता है: −9।
  4. -27 — (−3) × (−3) = 9, और 9 × (−3) = −27।
  5. 6 — तापमान 3 × 4 = 12 डिग्री बढ़ता है: −6 + 12 = 6 °C।

  2. (−4) × 5 × (−2) = ?

  3. (−36) ÷ 4 = ?

  4. (−3) × (−3) × (−3) = ?

  5. रात्री तापमान −6 °C आहे आणि दर तासाला 4 °C वाढते. 3 तासांनी तापमान किती होईल, °C मध्ये?

उत्तरे

  1. 10 — −8 + 15 = 7; −3 वजा करणे म्हणजे 3 मिळवणे: 7 + 3 = 10.
  2. 40 — (−4) × 5 = −20; (−20) × (−2) = +40 (दोन ऋण मिळून धन).
  3. -9 — 36 ÷ 4 = 9, आणि ऋण ÷ धन ऋण असते: −9.
  4. -27 — (−3) × (−3) = 9, आणि 9 × (−3) = −27.
  5. 6 — तापमान 3 × 4 = 12 अंश वाढते: −6 + 12 = 6 °C.

A worked example

Find (−3) × (−4) × (−5), and (−48) ÷ (−6).

  1. (−3) × (−4) = 12, a negative times a negative is positive; then 12 × (−5) = −60.
  2. (−48) ÷ (−6) = 8, because both numbers are negative.

Answer: −60 and 8. Check: an odd number of negative signs (three) gives a negative product; 8 × (−6) = −48.

The common mistake

Subtracting a negative as if it were a positive: 7 − (−2) is 7 + 2 = 9, not 5.
