4000 - 4 0^{2} - 20 \cdot 40 - 50

1550

Solution steps

4000 - 4 0^{2} - 20 \cdot 40 - 50

Follow the PEMDAS order of operations

Calculate exponents

4 0^{2} : 1600

4 0^{2}

4 0^{2} = 1600

= 1600

= 4000 - 1600 - 20 \cdot 40 - 50

Multiply and divide (left to right)

20 \cdot 40 : 800

20 \cdot 40

20 \cdot 40 = 800

= 800

= 4000 - 1600 - 800 - 50

Add and subtract (left to right)

4000 - 1600 - 800 - 50 : 1550

4000 - 1600 - 800 - 50

4000 - 1600 = 2400

= 2400 - 800 - 50

2400 - 800 = 1600

= 1600 - 50

1600 - 50 = 1550

= 1550

= 1550
