# Adding + integers - examples

- Mistake

Nicol mistake when calculate in school. Instead of add number 20 subtract it. What is the difference between the result and the right result? - Opposite numbers

Calculate opposite numbers (additive inverse) to given ones: - Thermometer

The thermometer showed -3°C at morning. Then temperature was increased by 1°C again increased by 1°C and then decreased by 1°C and then decreased by 4°C. Which terminal temperature thermometer shows? - With bracket

Calculate (evaluate) simple mathematical expression with a negative numbers and a bracket: 13+15*5-2*(-6) - Elevator

The panel house has ten over-ground floors and four underground. The lift goes from the ground floor to 2nd floors, then goes down to 3rd underground floors, then 9 floors up and finally 4 floors down. To what story elevator come? How many floors did it cr - Thermometer

thermometer showed -12 degrees Celsius at the morning then the temperature rises by 4 degrees and later again increased by 2 degrees at the evening has fallen by 5 degrees and then fall 3 degrees. What end temperature does the thermometer show? - Expression 6

Evaluate expression: -6-2(4-8)-9 - Brackets 2

Add parenthesis to make true: 5-2×6-4+2=5 - Evaluate expression 2

Evaluate expression with negatives: (-3)+4+(-8)+(-6)+4+(-1)

We apologize, but in this category are not a lot of examples.
