On Your OwnPor tu cuenta
Tables, mistakes to find, and problems with a few steps.
Tablas, errores por encontrar y problemas de varios pasos.
- Fill in the table
- Which statement about absolute value is TRUE?
- |-4| = |4| because both are 4 units from zero
- |-4| = −4 because the number is negative
- |-4| = 0 because negatives cancel out
- |4| > |-4| because positive is always bigger
- Confusing Opposite with Absolute Value
- What is the best next move?
- Report −35, because the submarine is below 0.
- Distance from −35 to 0: 35.
- Add −35 to its opposite: −35 + 35.
- Compare −35 with 0 and say which is greater.
