To solve for the area between the curves \( y = |x| \) and \( y = x^2 - 2 \), we need to follow these steps:

### Step 1: Find the points of intersection.
The curves \( y = |x| \) and \( y = x^2 - 2 \) intersect at points where they have the same \( y \)-value. This means we need to solve the equation \( |x| = x^2 - 2 \).

#### For \( x \geq 0 \):
In this case, \( |x| = x \), so the equation becomes:
\[
x = x^2 - 2
\]
\[
x^2 - x - 2 = 0
\]
Factoring this gives:
\[
(x - 2)(x + 1) = 0
\]
Thus, \( x = 2 \) or \( x = -1 \). Since we are considering \( x \geq 0 \), we have \( x = 2 \).

#### For \( x < 0 \):
In this case, \( |x| = -x \), so the equation becomes:
\[
-x = x^2 - 2
\]
\[
x^2 + x - 2 = 0
\]
Factoring gives:
\[
(x - 1)(x + 2) = 0
\]
Thus, \( x = 1 \) or \( x = -2 \). Since \( x < 0 \), we take \( x = -2 \).

### Step 2: Set up the integral.
The area between the curves is the integral of the difference between the two functions over the interval where they overlap, which is \( [-2, 2] \). We split the integral into two parts based on the symmetry of \( |x| \):

1. For \( x \in [-2, 0] \), \( |x| = -x \).
2. For \( x \in [0, 2] \), \( |x| = x \).

Thus, the total area is given by:
\[
\text{Area} = \int_{-2}^{0} \left( (-x) - (x^2 - 2) \right) \, dx + \int_{0}^{2} \left( x - (x^2 - 2) \right) \, dx
\]

### Step 3: Compute the integrals.

#### First integral (\( x \in [-2, 0] \)):
\[
\int_{-2}^{0} \left( -x - x^2 + 2 \right) \, dx
\]
\[
= \int_{-2}^{0} (-x) \, dx - \int_{-2}^{0} x^2 \, dx + \int_{-2}^{0} 2 \, dx
\]
Evaluating these integrals:

1. \( \int_{-2}^{0} (-x) \, dx = \left[ \frac{-x^2}{2} \right]_{-2}^{0} = 0 - \frac{-4}{2} = 2 \)
2. \( \int_{-2}^{0} x^2 \, dx = \left[ \frac{x^3}{3} \right]_{-2}^{0} = 0 - \frac{(-2)^3}{3} = \frac{8}{3} \)
3. \( \int_{-2}^{0} 2 \, dx = \left[ 2x \right]_{-2}^{0} = 0 - (-4) = 4 \)

Thus, the first integral becomes:
\[
2 - \frac{8}{3} + 4 = 6 - \frac{8}{3} = \frac{18}{3} - \frac{8}{3} = \frac{10}{3}
\]

#### Second integral (\( x \in [0, 2] \)):
\[
\int_{0}^{2} \left( x - x^2 + 2 \right) \, dx
\]
\[
= \int_{0}^{2} x \, dx - \int_{0}^{2} x^2 \, dx + \int_{0}^{2} 2 \, dx
\]
Evaluating these integrals:

1. \( \int_{0}^{2} x \, dx = \left[ \frac{x^2}{2} \right]_{0}^{2} = \frac{4}{2} - 0 = 2 \)
2. \( \int_{0}^{2} x^2 \, dx = \left[ \frac{x^3}{3} \right]_{0}^{2} = \frac{8}{3} - 0 = \frac{8}{3} \)
3. \( \int_{0}^{2} 2 \, dx = \left[ 2x \right]_{0}^{2} = 4 - 0 = 4 \)

Thus, the second integral becomes:
\[
2 - \frac{8}{3} + 4 = 6 - \frac{8}{3} = \frac{18}{3} - \frac{8}{3} = \frac{10}{3}
\]

### Step 4: Add the results.
The total area is:
\[
\frac{10}{3} + \frac{10}{3} = \frac{20}{3}
\]

Thus, the area between the curves is \( \frac{20}{3} \).
