• -10 degrees
• -20 degrees
• 10 degrees

Sofia owes her brother $25. She gives her brother the $18 she earned dog sitting. Write an expression then solve.

• 25 - 18 = -7 
• -25 + 18 = -7 
• 25 + -18 = -7 
• 25 - 18 = 7 

The sea surface temperatures range from -2 °C to 31°C. Determine the difference between the maximum and minimum temperatures.

• -2 + -31 = -33

• 2 + -31 = -33

• -2 -31 = 33

• -2 - 31 = -33

 Stephanie has $152 in the bank She withdrawals $20. Then she deposits $84.Find the sum in her bank. 

• 152 + 20 +84 = 256
• 152 -20 - 84 = 46
• 152 +20 - 84 = 88
• 152 - 20 +84 = 216

In the Sahara Desert one day it was 136°F. In the Gobi Desert a temperature of -50°F was recorded. What is the difference between these two temperatures?

• 136 - -50 = 86
• 136 + 50 = 186
• 136 - -50 = 186
• 136 - 50 = 86

What equation is modeled?

• 7 + -6 = -6
