Answer:
Problem 13: 7
Problem 15: 61
Step-by-step explanation:
PEMDAS stands for parentheses, exponentiation, multiplication/division, and addition/subtraction. For problem 13, you need to multiply 16 and 5 together first, giving you 80. Then you solve the problem left to right:
88-80+2-3= 8+2-3=10-3=7
For problem 15, first you raise 4 to the third power, which gives you 64. Then you divide 24 by 8, which gives you 3.
64-3=61
