Explain the meaning of each expression:

1. \(3<5\)

2. \(0>100\)

3. \(-3<5\)

4. \(-5<-2\)

Give the opposite of each number: \(5\), \(7\), \(1\), \(-5\), \(-8\)

Add \(3+(-5)\) using the number line.

Add \(-3+5\) using the number line.

Add \(-3+(-5)\) using the number line.

Add all combinations of positive and negative \(10\) and \(15\).

Simplify: \(10+(-5)+(-3)+4\)

Simplify: \([-3+(-10)]+[8+(-2)]\)

Subtract: \(-7-2\)

Subtract: \(\;12-(-6)\)

Subtract: \(7-9\)

Combine: \(-3+6-2\)

Subtract \(3\) from \(-5\)

Multiply:

1. \(2(4)\)

2. \(-2(-4)\)

3. \(2(-4)\)

4. \(-2(4)\)

Multiply: \(-3(2)(-5)\)

Expand and simplify:

1. \((-6)^2\)

2. \(-6^2\)

3. \((-4)^3\)

4. \(-4^3\)

Simplify: \(-4+5(-6+2)\)

Simplify: \(-3(2-9)+4(-7-2)\)

Multiply:

1. \(\left(\displaystyle\frac{2}{3}\right)\left(-\displaystyle\frac{3}{5}\right)\)

2. \(\left(-\displaystyle\frac{7}{8}\right)\left(-\displaystyle\frac{5}{14}\right)\)

3. \((-5)(3.4)\)

4. \((-0.4)(-0.8)\)

Divide:

1. \(12 \div 4\)

2. \(-12 \div 4\)

3. \(12 \div (-4)\)

4. \(-12 \div (-4)\)

Divide:

1. \(\frac{20}{5}\)

2. \(\frac{-20}{5}\)

3. \(\frac{20}{-5}\)

4. \(\frac{-20}{-5}\)

Simplify: \(\displaystyle\frac{-15+5(-4)}{12-17}\)

Simplify: \(-4\left(10^2\right)+20\div (-4)\)
