To evaluate the expression 1+13⋅2+5^2−3+15−3, we perform the operations according to their order of precedence.
First, we raise 5 to the power of 2, which is 25.
Next, we multiply 13 by 2, which is 26.
Then, we add all the values together:
1 + 26 + 25 - 3 + 15 - 3 = 62
Therefore, the evaluated expression is 62.

To evaluate the expression 4^3−4÷2+5, we follow the order of operations (PEMDAS/BODMAS).
First, we perform the exponentiation:
4^3 = 4 * 4 * 4 = 64.
Next, we perform the division:
4 ÷ 2 = 2.
Then, we perform the subtraction:
64 - 2 = 62.
Finally, we perform the addition:
62 + 5 = 67.
Therefore, the evaluated expression is 67.

To add 26 and -10.1, we simply combine the two values.
26 + (-10.1) = 15.9
Therefore, the sum is 15.9.
26 + (-10.1) = 15.9
Therefore, the sum is 15.9.
Subtract.
5.2−(−20)
5.2−(−20)
To subtract -20 from 5.2, we can rewrite the expression as addition:
5.2 + 20 = 25.2
Therefore, the result is 25.2.
5.2 + 20 = 25.2
Therefore, the result is 25.2.
